Microsoft: IE8 faster than Firefox, Chrome

But the differences are 'actually very small,' admits IE product manager

Microsoft Corp. said this week that its own speed tests prove Internet Explorer 8 (IE8) is faster than either Firefox or Chrome.

In a report released Wednesday, 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 google.com, facebook.com, amazon.com, 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 2.0.169.1 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."

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
