Microsoft Corp. says that its own speed tests prove Internet Explorer 8 (IE8) is faster than either Firefox or Chrome.
In a report released last week, Microsoft spelled out how it tests browsers in-house, and again stressed that it doesn't buy the idea that benchmarks -- such as those that score JavaScript performance -- accurately compare the players.
"These benchmarks necessarily characterize only a narrow set of the browser functions in a very constrained way," Microsoft's report said. "End users, however, do not operate in a controlled environment."
Microsoft's tests pitted IE8 Release Candidate 1 (RC1), which launched in late January, against Google Inc.'s Chrome 1.0 and Mozilla Corp.'s Firefox 3.0.5, a version from mid-December. The company timed how long it took each browser to completely render the 25 most-popular destinations on the Web, as ranked by the Web metrics firm comScore Inc., which included,,, and others.
IE8 was fastest in rendering 12 of the 25 sites, said Microsoft, while Chrome took second by beating the others on nine sites. Firefox, meanwhile, was a distant third, coming in first on just four of the 25 domains.
Microsoft did not test other browsers, such as Apple Inc.'s Safari or Opera Software ASA's Opera, said James Pratt, a senior product manager on the IE development team, because it wanted to focus on rivals that "had a good share on the Windows platform."
Both Opera and Safari for Windows have shares of less than 1%, according to the most recent data from Net Applications Inc., with the former, on all platforms, accounting for 0.7% and the latter just 0.3%.
Nor did Microsoft put IE8 in the ring with later versions of Chrome and Firefox. Chrome, for instance, is currently at as a developer-only build, while Firefox just rolled out 3.1 Beta 2. Both browsers boast better performance, specifically faster JavaScript rendering. "IE8 RC1 is a release candidate, and was very close to being done," explained Pratt when asked why newer versions of Chrome and Firefox had not been used. "But Google and Mozilla were still actively working on [those newer browsers], and they weren't super stable."
JavaScript benchmarks have become a point of dispute between Microsoft and its rivals. While Mozilla, Google, Apple and Opera have all updated their JavaScript engines in the last eight months, and have then trumpeted scores in JavaScript test suites like SunSpider, Microsoft executives have dismissed the bragging as so much noise.
Dean Hachamovitch, IE's general manager, has called claims of competitors a "drag race" that Microsoft isn't interested in joining, while Pratt has downplayed comparisons of any kind. "We're at the point, with what people do in the browser, that users can't really tell the difference between browser [performance]," he said in a January interview.
Pratt said that the just-released report backed that up. "As you can see from the scores, the differences between the browsers are actually very small," he said.
When Computerworld last tested the major browsers' JavaScript performance, immediately after the release of the public beta of Safari 4, IE8 ranked last.
Although Google did not respond to a request for comment on Microsoft's benchmarks, Mozilla's Mike Shaver, who heads all development at the company, applauded any attempt to boost IE's performance. "I don't think anyone here has had a chance to really look at their methodology yet or tried to reproduce their results, but to whatever extent Microsoft is working to improve the performance of IE it's a good thing for the Web," said Shaver in an e-mail late Thursday.

Good day:)
Great informative article on browsers.
Personally I favor Firefox to any others.
I tried Chrome but it did not really impress me at all.
So I stayed with Firefox.
Thanks for the info!

I can't believe they beat FireFox!

And as for Chrome, it looked cool, but couldn't all the things FireFox does...I mean I use some pretty helpful add-ons with FF and no other browser is coming close to 'em.

Good read and I see you went against the old Guru's grain by going with a black background ;-)

@Dorothy...thanks for dropping by, I use FF and Opera as inet browsers, tried Chrome also, but only for about 5 surfing

@Caleb...Astounding claim by Microsoft, I never bothered to try IE8 RC1 though, but i'm looking out for IE8 Final. But i've read there're improvements in IE8.
As for my template, intended for a different niche at the beginning, now seems to be
Thanks for dropping by, Caleb.

Once upon a time, I was an IE lover. Didn't even bother trying any other browser, until one day, I tried FF. FF is very good and I love my add-ons, almost can't live without it.

Since then, I have been trying hard for IE to regain my trust. I tried IE 8 RC1 and did not impress me at all. Recently I have downloaded IE8 and I am still testing it's new features. I will give you my opinion once I have a better feel for it. Nice wrap up you made here.

you have a very tech savy blog :)

@diTesco...As of now, i'm testing IE8's response at various websites, like video/movie sites, flash games, etc.
yup, can't tell the pros and cons at this time, friend.
