Performance Comparison of Major Web Browsers

Oct 14 2009 by Jacob Gube | 268 Comments

Performance Comparison

The latest versions of the five major most web browsers (Mozilla Firefox 3.5, Google Chrome 3.0, Microsoft Internet Explorer 8.0, Opera 10.0, and Apple Safari 4.0) went head to head under six performance indicators: JavaScript speed, average CPU usage under stress, DOM selection, CSS rendering speed, page load time, and browser cache performance. Each web browser was tested three times under an unprimed cache (except for the browser cache performance), and their average value reported in the results.

I still have to stick to good ol’ firefox when it all comes down to it.

Looks like Chrome hits the nail on the head in just about every category. Firefox seems to run almost as slow as IE. nice chart. Thanks for posting it. I’ve downloaded it.


October 14th, 2009

While I see that testing machine stats in the full-size graphic, I think it’s important to note in the story which machine and OS this is based on.

Eric B.

October 14th, 2009

Interesting to know. I’m pretty sure that performance would be affected by any addons installed, though.


October 14th, 2009

Chrome’s only fast cuz it is a barebones browser with barely any features.

Adam Fitzgerald

October 14th, 2009

According to the charts, Safari beat Firefox 4 out 6. Why is it that they are listed equal 2nd? Are some of the charts weighted more heavily?

André Leite

October 14th, 2009

I would like to see the same test on OS X

Mark Aplet

October 14th, 2009

Interesting test results. I would be curious to know what the results would look like for a Macintosh comparing FF, Safari, Opera, and Chrome (beta)

Jacob Gube

October 14th, 2009

@Adam Fitzgerald: They were given inverse points for getting 1st, 2nd, 3rd, 4th, and 5th place in each benchmark (i.e. 1st = 5 points, 2nd = 4 points, etc.). Firefox did well in terms on being relatively consistent and not going to extremes, while Safari never managed to rank 1st in any performance benchmark. It’s a rudimentary ranking technique.

October 14th, 2009

I assume these tests were done on a Windows computer. I wonder how Safari on a Mac compares to the others (minus Explorer, of course). Any chance you could do the same tests on a Mac?

My gut-feeling is that Safari on a Mac is much faster than Firefox for most things.

Dane Ash

October 14th, 2009

One thing that effects speed in firefox are add-ons. They use up a lot of memory. I guess all browsers were downloaded and tested as the bare software. Javascript css heavy sites do pretty badly on internet explorer hey.


October 14th, 2009

Firefox for me and its never slow lol


October 14th, 2009

And Chrome is victorious, that’s great to see that Google can help push innovation in Browser Applications after just a few iterations. Did you have a Mac or PC? I’m curious if the Mac development version of Chrome numbers differ from the Windows version?

Jacob Gube

October 14th, 2009

A Mac comparison would be great – I’ll see what I can do.


October 14th, 2009

Yes a mac comparison would be a wonderful idea since I have used both safari on windows and on mac and it is considerably better on a mac.


October 14th, 2009

Disappointed lousy IE….I wonder why people still using it. It department in the Big company, please force your staff to shift. lol


October 14th, 2009

Yes, I used Google Chrome everyday, and Firefox with various plugin for web development. Thanks…


October 14th, 2009

This is all well and good for Joe User, but when it comes to web development, Firefox is still the Gold Standard, even if it occasionally decides to eat up a gig of my RAM. I haven’t seen nearly the breadth or depth of useful add-ons for any other browser yet. (And I apologize to the apologists, but Chrome’s Inspector doesn’t even touch Firebug.)


October 15th, 2009

I did a SunSpider test on Mac with Chrome (pre-release) and Safari 4 last week and Chrome’s JS engine is about 1.5x faster than Safari. I did not do all of the other benchmarks however.

Doug S.

October 15th, 2009

Not sure why Safari and Firefox are tied. If you look at the scores Safari is usually pretty far ahead of Firefox and only loses twice by a very close margin.

To me what this test really says is WebKit is king and if you use it in your browser it’s going to be rocket fast.


October 15th, 2009

I love Chrome as a web user. So its great to see it on top. Great job Google. But as a web developer,I think firefox is the best.


October 15th, 2009

Thank you, it’s a nice chart

The Javascript speed difference is definitely noticable


October 15th, 2009

Synthetic benchmarks mean nothing in terms of browsing speed. Try loading up a couple of sites from identical machines via scripts and time them. So tired of this crap being put out there, if you actually try the browser you’ll notice Opera feels faster startup, shutdown, etc… than all the rest. If you want to benchmark it go ahead.. I prefer to actually use my browser.


October 15th, 2009

thank you for that comparison. What would be the conclusion for the “normal” user concerning performance?


October 15th, 2009

It would be interesting to see how the results differ on different OS’s.

Obviously it wouldn’t be possible to test IE on OSX, linux or Safari on linux for example, but Opera, Chrome and Firefox could all be tested.


October 15th, 2009

I like how there’s like 4 stats, with Chrome winning all of them – but when you look at page load time the thing that really matters you see that FFox is #1 haha


October 15th, 2009

Interesting to see Chrome 3 is faster than Safari again. They seem to be racing against each other and constantly going faster.
It’s only a good thing!


October 15th, 2009

Don’t see any major surprises here.. Nice tests, thanks for sharing them and confirming that IE is a **** browser.


October 15th, 2009

I think that nobody notices any differences in real word browsing when using ff, opera, chrome or safari.


October 15th, 2009

Interesting results, especially for real life page load times. I only see small problem: for 3 samples the confidence intervals (95%) are overlapping, so from statistical point of view all browsers are the same and those tests should not be used in “overall performance”.

Can you increase the sample size for “Page load time” and “Browser cache performance”?


October 15th, 2009

It really should be noted that Safari, in this case, is Safari for Windows. The performance difference between Windows and OS X is quite big, presumably because on Windows it requires considerable extra guff in the way of additional code to abstract away the Windows APIs.


October 15th, 2009

The last two tests are worthless, since they are too dependent on network latency. A better test would be to check this on a local network web site.

Testing each browser three times and averaging the values is also well below what you need to make some real results. It depends on how much the averages are affected for each x times you do the test.

Optimally the tests should be run on each browser until the averages for each test normalize. The results presented here are therefore only indicative and not conclusive at all.


October 15th, 2009

No IE6?! Haha


October 15th, 2009

Opera 10.10 is now definitely the 2′nd fastest browser. There is no way Firefox loads pages faster than opera 10.10.


October 15th, 2009

I’m suprised Opera is so slow in this benchmark O_o
I still love it. :D

Linux And Friends

October 15th, 2009

It is nice to know that in majority of the tests Google Chrome is doing quite well.


October 15th, 2009

this review is a sh#t. Chrome eats up your processor like a hungry lion.

this review is a sh#t. Chrome eats up your processor like a hungry lion.


October 15th, 2009

These charts are fun at most. Somehow the results are never the same as my own conclusion during everyday usage. I’m using Maxthon 2 (built on IE7) for normal browsing. It’s completely customizable and quite fast, making it my favorite browser. I use Firefox for web development and have installed a few add-ons for this purpose. Firefox is extremely slow for me (loading takes over 10 seconds). Chrome and Opera are nice and fast browsers, but they don’t have the good user experience Maxthon has, or the extensive set of plug-ins for web development that firefox has.

So, nice to see charts, but it all comes down to how a browser behaves in a specific area where it’s needed.


October 15th, 2009

Yap I love Google, I’m using chrome and firefox this browsers are the best today i think so.


October 15th, 2009

Fake, he works to google.


October 15th, 2009

Great post. Firefox should be in 3rd place though. Safari clobbers Firefox on many benchmarks which clearly proves the power of Webkit.

2nd: Safari
3rd: Firefox


October 15th, 2009

The latest versions of the five major most web browsers? No, you are not using the latest version of IE8.
I’m using a later version of IE8 (8.0.7600.16385). Try to make the test again with the latest version of IE8.
Do the test on MAC and Linux – you would get a different resultat (as JDM states).


October 15th, 2009

Chrome is semi-barebones for my taste. Simply put, there are add-ons and extensions for Firefox that I cannot live without. I wonder if Chrome is available in a portable version … hmmmm.

Carolus Holman

October 15th, 2009

Funny, You got IE 8 to Load? I have to start the Browser 2x 3x to get it to load a single page…


October 15th, 2009

You should add OSX Safari to the test.

I wish I could take IE out in the and shoot it.


October 15th, 2009

firefox i think uses up more CPU than IE8 in my opinion.i have all the major browsers installed on my PC xcept tht i choose to run chrome 4 instead of 3.even then firefox is the slowest to start.IE8 starts way faster than PC is Vista (32-bit), Pentium D @2.66 GHz and 3GB DDR2 RAM


October 15th, 2009

Not at all surprised by these results. On my work PC, I generally use Chrome for general web-browsing, though I’ll switch to Firefox to debug javascript (firebug, chrome’s inspector just doesn’t quite cut it) or fiddle with CSS.


October 15th, 2009

only bad thing about chrome is no google toolbar.

i’m waiting for the convergence…..

chromium o/s.

chrome browser.

google voice.

google mail.

google wave.

then hang on for the changing of the guard.

old computer dynasties either change with the times or disappear, remember wang or digital equipment?


October 15th, 2009

Chrome looks like a winner, but you left out the category of timing how quickly the browser can make itself completely vanish from your system without a trace. Chrome wins that one, too, and is the main reason I don’t use it.


October 15th, 2009

Nice chart. one of my classmates just did a presentation on chrome, and the data he used wasn’t nearly as good as this. However, I’m a web developer, so I’m sticking to firefox because it helps me get things done quicker. maybe if google releases a mac version of chrome, and opened it up to third-party plugins (it’s really hard to beat ff with fb as a web developer), I might consider switching. thanks for the info!

José Mota

October 15th, 2009

i would love to see Mac OS X benchmarking as well :)


October 15th, 2009

This article is very pretty and all but in the end its utter garbage.

You would need to test dozens of pages dozens of times to get anything even remotely concrete and even then its very questionable. But why bother actually going for accurate results when you can be lazy and warn people to use caution when interpreting the results…

Just another clueless tool making a quick and inaccurate comparison to get some page hits.


October 15th, 2009

What?! I think something went wrong with the Opera testing.


October 15th, 2009

thanks for this info.

“This is all well and good for Joe User, but when it comes to web development, Firefox is still the Gold Standard”

For many that’s true, though I personally have come to champion Opera for development. In my experiences it’s more accurate on standards ( as is Safari ) than either Chrome or Firefox, and it has developer tools just like Firebug that many have lauded as at least on par with Firebug.

I’ve encountered several items that have come up as CSS issues with Firefox and several Javascript issues with Chrome, which has unfortunately started to push both of them into the category of “update for” rather than “develop for” when it comes to web development – leaving my primary development to be done against Opera and Safari, then I do updates for Firefox / Chrome, and finally IE.


October 15th, 2009

Chrome = good but not 100%. and the way Google does the product life cycle probably willnot be out of beta for the next 5 years. FF has a stable base and has been the ‘under dog’ VS IE for sometime now. chromes got alot of ground to cover before it would be considered a contender.

As long the user is not user IE6 Im happy…


October 15th, 2009

You didn’t measure RAM usage, and that’s the most important thing for people with old PCs in the end…


October 15th, 2009

Anyone have word on when Chrome will be released for Mac?

Sami Susiaho

October 15th, 2009

This data is solid, but cannot be used as a test of which browser is the best. The benchmark speed of a browser has little to do with the usability. I am thinking of ease of use, available plugins, features embedded by default, security, stability and overall looks. The image of the company providing the browser is a major factor as well. Then there are the updates. While one might think that it is important to have frequent updates that are quickly in place to plug the security holes, the user might prefer less frequent updates and accept the increased security risk. That is, if the user cares at all.


October 15th, 2009

Why there is no info reg what plugins and addons are installed in every browser?
This influence performance a lot! Don’t U think so?


October 15th, 2009

This information makes me realise why some people still hold on to IE, I’m seeing that Firefox is losing out to Chrome in most respects, yet I’m still unwilling to leave it because I like it.

I think in a couple of years time Chrome will be at a point where it’ll be my default browser.


October 15th, 2009

Now, how about you run the same tests on Vista x64?

Andrei Patrascu

October 15th, 2009

Great article as always Jacob! Anyway chrome may be faster but I still like Firefox. Also Opera is a good alternative :).

Burak Erdem

October 15th, 2009

It’s so obvious that Google Chrome is the new king of web, and to tell the truth it really deserves this. For years I used Firefox just for its extensions. And now I’m very happy with my Chrome. I only use Firefox when I write HTML because of Firebug. Other than that I never start my Firefox.

Thank you Google for making such a great browser, and Microsoft for making our lives so hard…


October 15th, 2009

Opera runs alot faster on some sites with javascript off (onemanga!). Though this doesn’t let me browse sites that need javascript at the same time =/.

I still use opera because of some small opera features.


October 15th, 2009

just curious, who is the internet provider?


October 15th, 2009

If only Google made Chrome for Mac already :(

Eric Lau

October 15th, 2009

I love Google Chrome but it keep gave me blue screen from time to time….any one can help? I am on XP Pro


October 16th, 2009

I use Internet Explorer mostly only because I find that most websites look better in it. It is slow however but I am finding Firefox is getting just as bad. And I don’t use Google Chrome as it limits my search to Australia and for my online business I need to be able to search the US.


October 16th, 2009

firefox. Safari always drop the connection. (i’m on OSX)
Chrome is in development for OS X.


October 16th, 2009

Very interesting, didn’t realise chrome was such a bad ass when it comes to general performance… Personally though I find safari and firefox the best as I’m a mac boy. My websites always look better in these browsers. But surely there are many factors, like computer speed, broadband speed etc?


October 16th, 2009

Chrome rules. :-)


October 16th, 2009

results will vary depending on what your using.

carry out the same tests on a 3.06Ghz iMac with 4GB Ram and a really good broadband connection?


October 16th, 2009

i really like mozila and safari, IE have many problems they don’t solve yet, as a designer i always prefer both my favorite browsers, also accept comparison.

Jacob Gube

October 16th, 2009

Hello everyone. Just wanted to drop my two cents on comments regarding Firefox vs. Chrome. To me, the choice between Firefox and Chrome really depend on what what you think is more important: extensibility or performance. When I’m just browsing the web, I use Google Chrome because the sites and webapps that I like are client-side scripting intensive (Digg, Gmail, etc.). You can really tell the difference between Google Chrome and Firefox on Digg: page response times feel faster and the site feels more responsive. But when I’m developing, I use Firefox because of the extensions that it has. Google Chrome has a great tool like Firebug+YSlow built right in, but I’ve gotten used to Firebug and Firebug’s many extensions like FirePHP.


October 16th, 2009

“Resolving Host” still a big problem for Chrome. I don’t see how it can win any speed test as long as the problem exist!

Valdeir Gomes

October 16th, 2009

Hi I live in Brazil and here we use mozila firefox for enter BANK LINE cause his safety.
SO you can say any thinnk about security, which web BROWSER is more security.

PS. Nice article


October 16th, 2009

Yeah pretty good result and article . but sometime i got bad experience from all over the browser. that is all consumed 100% cpu as well memory too. then it will automatically stuck.

Ali Qayyum

October 16th, 2009

thanks for the information, i like firefox due to it’s customization features. i love it’s add-on. i got few tips from this link

Figures that IE would be at the bottom of the list:)

Oliver Mezquita

October 16th, 2009

Very interesting article. One more article to have handy when trying to explain why users should use IE as less as possible. I mentioned it in my blog.


October 17th, 2009

even though, i cant live without firefox addons.


October 17th, 2009

Thanks for the info. Only one question: what is Internet Explorer?


October 18th, 2009

wow.. thats amazing Congrat for Google

Sam Logan

October 18th, 2009

Interesting post, I wasn’t expecting Chrome to win by so much!


October 19th, 2009

yeah we can say google top everything but i have google chrome, i get crashes so far… i dont like it

a point millisecond difference of speed is not an issue to me thats why im sticking the Firefox; btw i manage to tweak my firefox memory issue using: about:config. plus ff is more reliable and also you have a wide choices of add-ons


October 19th, 2009

Hate IE with a passion!


October 19th, 2009

Based on my experience, Chrome is the fastest browser. However, Firefox’s features surpasses Safari and Chrome put together. To be fair, an average user won’t be able to tell significant difference between the 3 browser.

And now… IE. I’m sorry to say this but IE really really REALLY sucks BIG TIME. I hated it then, I still hate it now.

Anyway… I use all 3 browsers. I really appreciate Safari’s “Top Sites”. It gives a more sophisticated feel. Firefox’s add-ons are unparalleled. I find managing bookmarks in firefox the easiest. Speed and simplicity are Chrome’s selling point.

Thanks for your review… =)


October 19th, 2009


Nice but you did not mention anything about memory consumption. So I did it:


October 19th, 2009

Personally I use Opera and I find it quite fast though not as fast as Chrome at some tasks. That said, I find a couple of problems with this test. Please let me know if I am mistaken.

- CPU usage is measured when running Sunspider JavaScript test. That seems to be only one way to measure CPU usage and the task manager also seems a less scientific way of determining CPU load
- Page loads test is only tested on frontpage. This is far too limited a selection.
- Page cache performance is also only done for 1 page when browsers like Opera have very evolved page caching mechanisms.


October 19th, 2009

wow, never try any other browser except fire fox and IE, and its more confortable using firefox than IE. but this post made me curious to try the 2 others (Google Chrome, Opera 10.0)

Lee Munroe

October 20th, 2009

Nice work Jacob. Had no idea Chrome was so good


October 20th, 2009

Wow- guess I’ll have to try Chrome again. Still like my Firefox though, and no surprise with IE – oink oink!


October 21st, 2009

in my opinion firefox is the best browser


October 21st, 2009

It would be interesting to see how standards complient all these browsers are in conjunction with a test like this.

Mike J made the statement of using Opera for development, I have to agree with him I do the same.

Obviously standards will not affect performace and memory etc. but it would give you a nice “overall view” of capabilities.

PS – Nice job.


October 21st, 2009

Performance is only one functional criteria. Chrome dosen’t have a 508 compliant interface and doesn’t have an proper rendering engine to handle all the varaitions in html markup.


October 22nd, 2009

Firefox it is for me and has been for the last few years.

Had a brief look at chrome before and may have another look based on that performance.


October 23rd, 2009

One thing to bear in mind for this test. Chrome is not the typical browser compared to the rest. I mean as part of Google’s plan, eventually Chrome will be the window (no puns intended) to their cloud infrastructure where applications will be hosted. So its not the normal firefox/IE browser.


October 26th, 2009

You neglect one area: memory usage. Chrome is a huge memory hog on Vista, which is ultimately why I switched back (ironically) to Firefox.


October 28th, 2009

I use Mac Firefox almost exclusively. I’ve had some stability
issues, and it uses too many resources, but with Adblock Plus and Flashblock, it has the best mix of performance and features.


November 1st, 2009

Very interesting graph. Although I knew already that IE would probably be the worst I was actually pretty surprised that Chrome overpowered Firefox. Until now I was pretty sceptical about Chrome.


November 4th, 2009

I tired of seeing these kind of benchmark when FF and Safaria have huge memory leaks… How many time did I have to close and open them to free almost 1GB of memory… When using 1GB, the whole OS become slow and FF and Safari freeze for a while then come back… Please I don’t care about 1ms of CSS rendering… but I care about the long minutes FF or Safari freeze then comes back and the long minutes I spend restarting my browsers…


November 10th, 2009

Dear Jacob I must disagree with you because I consider this test a little irelevant and here’s why :

Google Chrome may perform better than other browsers on a single OS.

What about testing the same browsers on different computers with different amount of RAM, CPU etc. and also on different OS such as :

Microsoft Windows XP
Microsoft Windows Vista
Microsoft Windows Server 2008
Microsoft Windows 7
Linux ( all major distros )
Mac OS X ( different versions )

As far as I know Google Chrome is being optimized for the web experience but doesn’t have all the features of other browsers.

It’s my personal opinion and I could be wrong but I don’t think so.

Kim H

November 10th, 2009

Only issues I have:

1) Chrome does not come for mac.

2) Firefox crashes far too easily.

I’ve generally been using mostly Safari; I just don’t like that it doesn’t tend to save my tabs like other browsers do. At other times I use Opera, but I greatly dislike its apparent slowness in rendering JS.

Other thing is, I like Firefox’s plugins, so I tend to use it most for developmental work than I do other browsers; it’s really nice being able to edit code and troubleshoot in the same browser.

Nice work.


November 14th, 2009

I thought so. Chrome is amazing.


November 16th, 2009

I’d like to see benchmarks run for XP and 7…
Friends don’t let friends use Internet Exploder…


November 20th, 2009

How true. the only i us Firefox for long session on the web and Chrome for short. Firefox’s plethora of add-ons just make a long session easier and put every thin i am interested in in a few clicks (and thus the least amount of time) possible.

But if i just nee a Movie look up off IMdB or a recipe i hit up Chrome.

If i want to have suicidal thoughts i will go with IE… nit i do no want suicidal thoughts.


November 22nd, 2009

You should throw Epiphany in the mix and see if chrome still comes out on top.

Jonathan Harley

November 24th, 2009

Crazy, IE 8 doesn’t feel that slow – but I use Chrome when I can anyway..

Maybe it’s not surprising because most of the differences (as opposed to the biggest differences) are in 10s of milliseconds; barely enough time to blink..


November 27th, 2009

Few surprises here. But why does a developer of Microsoft’s calibre, with their experience, market share and, presumably, the pick of the graduate programmers consistently produce such a lousy web browser? Seriously, I cannot get my head around this at all.


December 4th, 2009



December 4th, 2009

If in the results there is a joint second shouldn’t the next place be forth not third?


December 7th, 2009

This just confirms that IE is actually internet exploDer!
I think i´m still going to use Firefox because of the amount of addons you can have.

Lyons s

December 12th, 2009

I sometimes find firefox a bit annoying, however IE is worse


December 16th, 2009



December 30th, 2009

How about running the same tests on OS X and Linux?


January 10th, 2010

I’d have to disagree on some of the results. I run an older single core computer and actually Firefox has a much worse page load time then chrome and opera.

To improve the results of this, I’d run the tests on more then just one computer on more then one platform.

I currently use opera, since firefox ran very slow on my older computer.


January 12th, 2010

In terms of CPU usage on OS X, it looks like Safari < Firefox < Opera < Chrome.

The current release of Chrome uses quite a lot of CPU time on the Mac implementation, but it's early days. I stopped using it after the first try, having opened up all the same tabs I had open in Opera (about 30), when the collective CPU usage of all the Chrome processes hit around 30-40%.
And Opera uses quite a lot of CPU already.

Also missing from this comparison is physical memory use – Opera on my 2 gig Macbook is currently taking up 374 MB, and often goes somewhat higher, but I have a lot of tabs open. Firefox and Safari OTOH tend to use significantly less RAM. Important if, say, you have a laptop which, although produced in 2007, will only hold a maximum 2 gigs of RAM (thanks Apple, clowns), and you're programming in Eclipse or some other memory hog IDE!


January 13th, 2010

I like Google Chrome for every day browsing but there are still some websites that don’t work with it. I often find myself loading up Internet Explorer just so I can do a transaction.

Joseph Jaber

January 13th, 2010

Why bother to test such a thing? Chrome and Safari have the superior rendering engines. Chrome is typically behind a little on their Webkit builds. Gecko doesn’t hold as much sophistication and support for modern CSS or HTML5, Gecko still has display quarks. Trident is non-standards compliant. Whether or not the browsers could pass the Acid test or any real performance factors haven’t been displayed.

Safari is out of element on the OS side, and Safari also has specular loading, so it’s not going to pull data onto a page until it gets dependant effects and/or jquery scripts or spriting. (and this defense is coming from a Chrome user)

This isn’t necessarily unhelpful, but it is certainly a straw man argument, that should, in no way, shape, or form, be considered by a web developer.


February 1st, 2010

Good Results Mate, Still i fix to firefox. Thanks for the Update.


February 8th, 2010

I used firefox with my browser for secure browsing


February 12th, 2010

I do not agree with the superiority of Chrome’s performance. I could not use it due to problems with it and rolled back to Mozilla Firefox.

Dev Basu

February 19th, 2010

While I love Chrome’s speed overall it still does not beat Firefox in terms of sheer versatility. When that day comes around, I’ll be more than happy to switch.


February 23rd, 2010

Dude, it was tested on a Dell. I wouldn’t trust this if I were you. Dells can’t do crap.

Tried Chrome but something missing, not sure what.

By the way, who or what is Internet Explorer, are they new, are they any good !!

Not a power user. Running XP on pentium4, Biggest computer error in last 10 years: allowing IE to upgrade to IE8. Now I’m singing “Wasted days and wasted nights” trying to do anything on the web. My neighbor’s dog crapped a better browser on my lawn.

Not a power user. Running XP on pentium4. Biggest personal computer mistake in the last 10 years: allowing IE to upgrade to IE8. Now I’m singing “Wasted days and wasted nights” trying to do anything on the web. looking for something better—better like in no lock-ups, crashes etc.

Do you know why give me 2.25 to 2.5 mbps download result when using Chrome, if I’m under a phisically limited adsl connection of 1.72 mbps (I’m connected through an ATM dslan) while any other browser show correct results?


March 27th, 2010

Nevertheless, Chrome sucks.


March 27th, 2010

nice web browser comparision but i think the web browser difeers from what computer you are using for me i think the best browser for Mac osx is Safari and firefox and both are configurables (ff aboutconfig) and safari through terminal opera is the best in windows less crashes and stuff i sincerily tested chrome but is like browsing on a paper sheet too plain
Im not either a professional im just a student from college :)

Interesting results. I found Chrome quite good until the updating and constant reporting kicked in soaking up my cpu power (single core processor) and causing pages to hang for up to a minute -rather different to the benchmarks. Had it been configurable then I might have continued but after being frustrated I removed it form both my desktop and laptop sorry but it makes a mockery of these results. Now well I have a choice of Opera, Firefox or if I suffer from incompatability issues IE


March 30th, 2010

it will be interested with the newest version of browser (opera … ).
There has been a lots of improvements since these results.


March 30th, 2010

one thing that isn’t tested that really should be is safety. although i don’t think it would change the results much. in my opinion chrome firefox and safari and all about equal in terms of safety and opera and IE are 2 browsers that should never be touched unless you don’t plan on keeping your computer long.

in response to mikeeeee: i know you’ll probably never read this but chrome can do everything that the google toolbar can do but in a more practical manner and without the ugly toolbar getting in the way. the URL bar doubles as a google search bar. upon entering a page written in another language chrome will as if you would like it to be translated for you.

i’ve honestly never been happier with a browser than i am with chrome. the only thing i would like to see is a functional FTP client add on like fireFTP on firefox but i’m sure that will come soon enough with the addition of extensions.


March 30th, 2010

too bad they don’t mention how much of a RAM hog chrome is


March 30th, 2010

Just proved what I always thought. I use Firefox and Chrome most of the time, followed by SeaMonkey and Flock. Only until they are exhausted, do I consider that other browser.


March 31st, 2010

wouldn’t testing safari on a PC be different than Mac, which is what most safari users run it on??


April 1st, 2010

Chrome has great peformance
Firefox has many plugin

I use both


April 2nd, 2010

firefox tweak to the limit is the fastest i’ve seen , i got my own tweaks and do not use the conventional tweaking , for me it’s the only browser i love to tweak and the os doesn’t matter


April 2nd, 2010

different browsers use different amounts of RAM. The more ridiculously fast a browser is the more RAM it takes……i prefer Safari on mac OSX. it’s fast, smooth, and reliable. I have found Chrome, on the other hand, no matter how fast it is, to be unreliable on my macbook pro. I use firefox just to watch DIVX movies.


April 3rd, 2010

I’ve been using Firefox for quite some time now but of late it has mysteriously crashed, not opened pages in Google or Adobe. Despite having emailed them I have yet to receive a response, so what’s the purpose of all these updates?
Chrome? They should name it Ruin, what a waste of time!


April 3rd, 2010

i would have to stick with firefox or IE for a powerful and robust experience. yet google chrome is a good for dev and jscript tools while Opera hits the charts in the netware and novell old at atx hybrid sys.


April 3rd, 2010

I am still not convinced as Google chrome has some bugs which are yet to resolve so i still prefer firefox over google chrome


April 4th, 2010

Chrome FTW! oh, baby!


April 5th, 2010

Hi 5 all… super cool tool especially for newbies never to soon to really understand the power of and in software tools…

Wilson Cowden


April 5th, 2010

I was having significant performance using Chrome when I installed some plug-ins. One of it is actually very annoying, when I switch between tabs, it takes some seconds the page to be display, which is not happened with Firefox even if its bloated with plugins. I don’t know about Opera (every version I use always crash) or IE (testing only) though.

William Foster

April 5th, 2010

Not suprised I don’t see Seamonkey here. My favorite browser, but not a very popular one.


April 6th, 2010

as a web dev i’ve had multiple browsers on my machine for years and my results differ from yours. From clicking on a browsers short-cut to having it loaded and on the desktop ready to use Firefox is by far the slowest followed by Opera – in the same time these take to load i can call up Maxthon and load a web page.

Any Mozilla based browser is most likely to not show the page correctly as it dictates font type and size, and until recently struggled with divs, overiding the html of the website you visit, consequently this can lead to texts and objects not to show. eg – if a page has a div with a specific font and size followed by a button, Mozilla browsers overide the font settings so may show the wrong fonr at the wrong size which forces the button out of the viewable area. As such i find it to be too unreliable for normal use and i just use it to check my own work displays correctly.

I hate to say it but i just never have any problem with IE (apart from the fact it’s made by MS), it always shows websites as they were designed to be seen. Older versions could be unstable which was why i started to use Maxthon as my main browser about 6 years ago.

In terms of usability and customisation Maxthon has had features which FF, IE, and Opera have only just caught up with.

Chrome reports everything you do back to google so i won’t have that on my machine on principle.

Firefox has the most useful plugins etc.

Opera does seem to be the fatest for general sufing, but is the least configurable.

I’ll stick with Maxthon as it’s fast, reliable, and configurable.


April 7th, 2010

this is out of date now. opera’s newest JS engine is the fastest.

Mike from Shreveport

April 7th, 2010

I like Google Chrome for speed–but it’s also the newest one of the group. My concern is that with feature bloat and code bloat they will “improve it to death” to the point that it’s no faster than the others. Opera used to be “the fastest browser on Earth.”

Well, we’ll see; time will tell. They ARE Google.


April 8th, 2010

Opera 10.5 ;)

Bache GDL

April 9th, 2010

Forgot to mention that Google Chrome is the one that crashes most along with Exlporer, while it is extremely fast, there has been issues lately using gmail with the Google Talk, plug-in.

As for Firefox well have more than 4 tabs open and off goes your RAM


April 10th, 2010

Mr. Google…is this you sending me your XV century adverticement?

Guust Flater

April 10th, 2010

Seen other tests where Opera is the fastest….


April 10th, 2010

Perhaps the most pathetic part of all this is that IE, after its “head start” of being bundled into the operating system, still fared so poorly compared to the rest.


April 10th, 2010

I switched to Chrome a few weeks ago and yes I miss the Firefox add ons but for speed and stability I will stay with Chrome.


April 11th, 2010

I think the moral of the story is IE still sucks and any of the other browsers are adequate enough to browse today’s internet.


April 13th, 2010

I use IE8 with Windows 7 every day with no issues… ever. I’ve used/tried Chrome and Firefox. They are just not as good as good ole Internet Explorer. FireFox was constantly updating plugins. That was so annoying I had to uninstall it. I forgot why I uninstalled Chrome, but I’m sure it was just not as good as IE or I would have kept using it. IE can get real slow if you install a bunch of crap toolbars and plugins. I keep it tight with Google Toolbar, McAfee SiteAdvisor, StumbleUpon and that’s it. It’s fast as hell and never crashes. I can’t see the need for any other browser.


April 13th, 2010

Any idea how sensitive your results are to the OS, etc? Considering it is an uncommon setup, I wonder if translates to the browsing population in any meaningful way.


April 14th, 2010

Safari was designed for MacOS, and Iphone, and surprisingly, it is reigning second in PC too ! It is tempting to see the comparison on MacOS or even Iphone.


April 14th, 2010

This is awesome, thanks a lot. I love Google Chrome!


April 14th, 2010

I love Chrome! The only thing I’m waiting for is some of my favorite plug-in’s from fire fox. Just a matter of time and I’ll be running only Chrome.


April 14th, 2010

I don’t know how to choose a Internet broswer. But most of our friends will use the IE because it has been installed when we buy a PC. So now My coputer will use it but my office work’s choice is firefox.

Beda Sorin

April 15th, 2010

I still trust in Firefox (most disposable) follow by IE 8 and opera.. only mini for mobiles have some good points ..somehow weak then “Bolt lite”!


April 18th, 2010

Agree, Google Chrome is the best, fastest and thanks to Google…


April 19th, 2010

You might want to add a graph of which one crashes the most. And I think that would;d bring chrome down a notch. Anyway I prefer Firefox.


April 19th, 2010

men i knew it…… !! google chromes d best…i would prefer google chrome over any website….;)

Bryce P

April 19th, 2010

Yet some 70% or better of users, depending on geographical location of users of sites tested, stick with IE. Are there just that many people that don’t care to find a better web experience or what? IE has been crap forever, I can only guess that most of those users just don’t know they have another option.


April 20th, 2010

Thank you for the comparison. Chrome might be the fastest, but especially for developer there is only one browser to choose: Firefox…. i love it.


April 20th, 2010

I am a web dev and I never use browser plugins. Firefox WAS good… now it is much too slow. They are adding too many bling-bling to it. On a Mac I use Safari, but Chrome is interesting and a bit faster.


April 20th, 2010

I would love to see a revised test with the latest versions to see if they still rank the same.


April 20th, 2010

Maybe if firefox could stop crashing it might start coming close to chrome


April 20th, 2010

Chrome is the fastest
but cannot integrate with Internet Download Manager 5.17
it’s sucks man! :(

if google could fix that only downside, I’ll use Chrome anytime. Yeah

I usually use Firefox

Nikhil Sheth

April 21st, 2010

Chrome and Firefox rocks. IE has a long way to catch up. Lets see if they can fare better with IE 9.


April 21st, 2010

Opera 10.51 outpersorms all.. IE9 beta too rocks


April 23rd, 2010

You should run a test on Linux and compare how much faster and smoother everything will be. ;)

Eco Freindly

April 23rd, 2010

THt’s gr8 statistics

But I diasgree on one thing

FF makes maixmum utilization of CPU and memory compared to other browers. Its occupies atleast more than IE

Rapi Castillo

April 24th, 2010

Firebug rules over all though, so.


April 25th, 2010

Was there any need to test IE for performance.
Thats already sucks and we know it. :)


April 25th, 2010

Great tests. Can we get an update with new browsers? (FFox 3.6, Opera 10.51, Chrome 4, etc.)


April 27th, 2010

Very nice to see how chrome is getting their part of the cake


April 29th, 2010

i loooove my google chrome ^.^


May 1st, 2010

The performance of Firefox in a linux OS also must be considered.


May 2nd, 2010

i,m use mozilla firefox.. and i love it


May 4th, 2010

Great charts, this is just the kick i needed to try out chrome. I shared this fine browser roundup on facebook too, i had no idea chrome was so much faster than IE.


May 4th, 2010

An update of this test with latest versions on Windows 7 64bit (mainstream PCs), and also same test on Win7 32bit (netbooks) would be great.

Anthony Pittarelli

May 11th, 2010

Anthony is proud of you Safari!


May 15th, 2010

You know, those last two in Overall Performance should say 4th and 5th, not 3rd and 4th…


May 19th, 2010

Nice to see the comparison of browser and their ranking. good.


May 19th, 2010

Great information very useful not just the test data but also your preferred use of FireFox and Chrome.


Jovino Margathe

May 25th, 2010

I used your article as a basis on my article on 2010 browser comparison, using a more updated versions of the browser. I’m using 64-bit Win7 and surprisingly, IE wins on the startup time from cold-start.

Overall, Opera is the winner but somehow it just doesn’t render webpages correctly.


May 29th, 2010

I started using chrome on a full time basis approximately 3 months ago and will not turn back the clock. Chrome is a great Browser and everyone should convert.


May 31st, 2010


On my PC, when I open more than 10 firefox tabs, it will crashes.
But, with more than 5 Opera windows with more than 20 tabs in each, It uses less than 200MB ram and less than 10% CPU usage.
But you say, Opera is as shit as IE?!

This benchmark is just like a joke!


June 1st, 2010

nice share….
i like google chrome


June 8th, 2010

Why the heck you would you test these browsers on such a shitty OS please try again on XP or 7 or even OSX. not that bastard child vista.

Nicolas Villaume

June 12th, 2010

Great work. I am wondering if others have seen much inconsistency in Chrome layouts yet. Despite the high ranking, I have seen some strange behavior.


June 13th, 2010

Why the hell would you test safari with a DELL?!?!?!?! Sorry, I think you’re a freaking idiot.

Nicholas Norton

June 13th, 2010

thank you for this valuable information.
personaly I prefer FF, it offer a lot of extension.


June 14th, 2010

this is old information , right now Chrome and opera 10.50 are with the same speed !


June 15th, 2010

Go Google Chrome! Soon we will see the Google OS overtake windows.


June 20th, 2010

This is a fine article. The graphs tell all.

I was wondering though, if you did the top FOUR browsers (minus IE) on a Linux and/or OS/X system what it would turn out to be?

Pablo Mendoza

June 20th, 2010

Maybe it’s time to update some data. Now Opera is faster than Chrome and Safari too.


June 23rd, 2010

you should have update your Opera to Opera 10.60 Beta and you’ll see the difference.

Jacob Gube

June 23rd, 2010

Just to make it clear: I may do a follow-up, but I’m not planning on updating this particular graphic. The version numbers are indicated here, and the date of publication is stated above. Things may or may not have changed, but I’d like to keep this as a “screenshot” of the performance of browsers at this particular point of time, rather than constantly updating it every version change.


June 29th, 2010

Cool comparison! I wonder how much Safari 5.0 would improve it’s performance against Chrome?


July 6th, 2010

I guess CometBird beats them all. CometBird is insane brothers. I mean how could you ignore such an awesome website pals.


July 6th, 2010

Not a surprise > Chrome is a lite, Firefox is a full browser…


July 7th, 2010

This all depends on the machine you use and your connection. If you have a slow connections certain browsers will work better.


July 8th, 2010

Chrome just has a good feel to it. Google and Android are taking over, and I am going along for the ride!


July 10th, 2010

I stick to Firefox because I’m used to it and I don’t know if I can “survive” without its addons. Next would be Chrome, but with all these rumors about Google spying us…
The rest, Opera and then IE of course.

Good post, btw!

kunal singhania

July 13th, 2010

it is really nice proof to say chrome rocks… :)


July 13th, 2010

I dont know about these stats.. From personal experience I have used them all and I find Opera much faster than any of the others. Also I do not like thedata that google collects on people and their browsing activities. Sort of big brother and I am sure that there is a whole dtabase set up somewhere with all of our info that is sure to be leakedone day. You’ve been warned


July 13th, 2010

All very well and good but despite performance GOOGLE IS STILL EVIL

Google is trying to take over the internet and for that reason firefox wins for me everytime. I will most happily sacrifice 500 odd ms in java loading in not supporting the wannbe monopolisers(sorry for spelling).


July 19th, 2010

For many years, I use Opera and I still consider it the best option. I worked some time for Chrome and Firefox, but did not impress me.

Adriano Ellero

July 21st, 2010

best comparison I’ve never seen.
can we update it systematically?


July 26th, 2010

And that’s why I use chrome!

Philip Treacy

August 10th, 2010

Cool comparison. So many of my clients still use IE, they just don’t know any better and have never been offered an alternative


August 18th, 2010

Excellent information
In future also continue to furnish this type of information
Please provide me with free down load of operating system


August 23rd, 2010

Well, I wonder how Opera can perform so poor, as far as overall user experience is considered I found it the fastest, even in terms of opening the tab, I have also found it to be taking the least memory when a lot of tabs are opened.

It would be nice to see the memory comparison and the existing tests when Opera Version 10.61+ is used.


August 24th, 2010

Opera works very well on my Wii but I have to agree with this comparison for a desktop running Windows 7 Ultimate, Chrome is the fastest thing out there


August 25th, 2010

I’m a web developer and i use all of them to check our websites. The Opera (10.61)is the much faster than any other browser.


September 5th, 2010

Chromium is the FASTEST browser !!!
Not Opera or Safari…


September 8th, 2010

Chrome is on the top. But I prefer working on Firefox.


September 9th, 2010

What this chart doesn’t have is any indication of what the scale of the overall issues are. For example, if all 6 tests were applied on rendering one page, would the the slowest browser take several seconds longer than the first to render? Or fractions of a second? Performance is important, but just putting things on a scale doesn’t really indicate if the difference is truly signifigant or just a difference that users could care less about.


September 12th, 2010

We still love Firefox, but definetly looks like Chrome is taking big strides!


September 15th, 2010

Firefox is way faster than chrome on my pc


September 21st, 2010

I’m using W7/HP with IE8/M.S.E. are running fast and smooth. no issues at all. that what Bhushan say.

Jørgen Reitan Sivertsen

September 26th, 2010

Good article, but when will we see an update? Opera claims to be the fastest browser on earth now, we need a new test!

this is so inaccurate!

September 30th, 2010

cute comparison. i decided to switch over to chrome after reading how much less cpu it used. i was tired of firefox eating up 60%+ CPU on my mac. at first chrome was looking good, with only 20% among all it’s threads… but then when a flash page was opened, i scrolled down and saw that the “Shockwave Flash (Chrome plug-in host)” was using 90% of the CPU!!! total crap. is there no browser out there that can consistently use less than 25% of CPU with lots of tabs open?


October 2nd, 2010

You have done a great job with this browser comparison. However The current date is October 2, 2010. All the browsers have undergone revisions. Would you please be thoughtful and revise the browser performance figures please. Thank you


October 5th, 2010

I agree with Warren – I would love to see how IE9 / Chrome / FireFox4 stack up!


October 12th, 2010

Look at that- Chrome wins. no surprise.


October 14th, 2010

Tried chrome, firefox, seamonkey, chrome much much slower on downloading files it does not have an option to continue on failed downloads nor firefox I prefer seamonkey on downloading files as I could pause or continue on a file later on. seamonkey wins. imho…


October 14th, 2010

I see this is old, you should see how awesome chrome is now since they are on like vers 5.0 now!


October 29th, 2010

i still comfort using firefox however


November 2nd, 2010

Chrome might be fast but it skews many websites all over the place. Well written websites included. Simply yelling that any website that doesn’t display perfectly in Chrome is poorly written is insane. Chrome is poorly written. I don’t like it.

Robert Bradbury

November 11th, 2010

Two tests which are critical for any browser (a) How much memory is consumed with a large window/tab load and (b) How much CPU is consumed (when idle) with a large window/tab load?

Wimpy single page load & display times do not reflect *real* world browsing and research activities which can involve 50-100 open windows and 500-800 open tabs. Sessions of those sizes are those which press on virtual memory performance as well as CPU overhead. It is very easy to bring even a modern machine to its knees if a browser session size reaches 50-75% of available RAM or if many tabs include scripts which require “active” polling. This generally effects all of the browsers listed with the exception of Safari (which I do not use). These statements apply to common machines like HP Pavilions from 3-6 years old. If one has to upgrade ones PC to use a “modern” browser then it isn’t a very good browser.


November 11th, 2010

IE sucks…


November 15th, 2010

love firefox..try google chrome


December 23rd, 2010

Google is very fast, yet I prefer the desin and functionality of Firefox! IE always had too much security leaks.


January 15th, 2011

Show the people why they should avoid using Internet Explorer:


February 2nd, 2011

Well everything makes sense except CPU usage…… i am not an expert but the taskbar shows multiple chrome tabs as seperate processes, when i did a comparison on memory usage of these, i found maxthon to be the lightest browser followed by opera and then firefox. i had 5 tabs open,, zapak another and redbull website, clearly chrome showed a lot more memory and CPU usage.

Also, IE 8 was the quickest to load redbull website. like i said, i am not an expert on how browsers work, nor was i testing javascripts. my units of measurement might not be useful parameters to measure either, but i know chrome occupies more memory than others.

I will continue to use chrome though, it gives my less problems with scripts, which eventually is the most important factor


February 7th, 2011

I’ve changed the pipelining information on my firefox browser which makes it incredibly faster.

Run Firefox. Type in “about:config:” search “pipelin”

Change “network.http.pipelining” to “true”
Change “network.http.pipeling.maxrequests” to “30″
Change “network.http.proxy.pipelining” to “true”

Right-click, Do “new-integer”

Name it “nglayout.initialpaint.delay” and set it to “0″

It will make Firefox faster, not sure how it would work against Chrome though.


February 21st, 2011

These results are not surprising to any regular Chrome user. :) I never have a problem with a page not loading correctly. When Chrome was new I would have to carry around two browsers, but that is not necessary now.

Sync bookmarks. Use the omni bar. Browsing bliss.


March 9th, 2011

I’ve been using Opera for the last few years and I was very pleased. There were inconsistencies in viewing web pages, but I managed to live with it. Since Chrome came, I forgot about Opera. Chrome beats all other browsers. Chrome is fast and clear – all what I expected from a web browser.


March 11th, 2011

Heh nice results. I agree with them.
Note that I am using Firefox, Chrome and Opera on my computer so there’s no “bet browser”.
Actually IE is so slow for me so I am NOT using it


March 17th, 2011

Why didn’t you guys use the latest browsers?


March 22nd, 2011

Conveniently left out the fact that chrome’s cpu goes up 100% for every new tab opened…

Nam Tien

March 26th, 2011

This article’s useful with fair & statistical info.
Currently, i’m a fan of Chrome. Vote for Chrome !



March 28th, 2011

No broswer is better than IE for me, Specially IE.v9 for fast speed and more secure an easy to use :)



April 6th, 2011

Benchmarks from more current versions available here.


May 8th, 2011

what about internet explorer 9?


May 16th, 2011

Firefox 4? I believe a new test must be done that is more current

Darren Mercer

June 9th, 2011

No browser is better than Firefox in my view, because Firefox has several features that other browsers are still missing.


June 16th, 2011

i think the latest version of firefox that is 5.3 beta is a better option than chrome if you concentrate on speed it loads pages faster than google chrome but firefox is lot behind on downloading speed

Kuzey Güney

June 21st, 2011

Yes, I used Google Chrome everyday, and Firefox with various plugin for web development. Thanks…

If IE were Obama it would be blaming everything on Firefox and Chrome. lol.

September 15th, 2011

I used chrome…Chrome is the fast :)


September 15th, 2011

it loads pages faster than google chrome but firefox is lot behind on downloading speed

Chrome is the fast :) chrome but firefox is lot behind on downloading speed


October 2nd, 2011

This is a wonderful content. I will bookmark this site and visit again. It is very informative. Thanks for sharing.


October 7th, 2011

I am a Chrome user for about 1year now, I have no any problems with Chrome, this is the best browser next to Firefox and Opera, the rest are garbage.


November 21st, 2011

Great analysis. When was this benchmark created and do you update it regularly?


November 25th, 2011

I always use firefox.Its super browser.Have some minor bugs but they always updating their software.
