Firefox Speedens

Firefox 3.0 Beta 4, which Mozilla released late Monday, has been put through its paces by users and bloggers, some of whom have published the results of head-to-head benchmark tests between Firefox, Opera, Apple Inc.'s Safari and Microsoft Corp.'s Internet Explorer. According to Percy Cabello, who posted his results on the Mozilla Links blog, Firefox 3.0 Beta 4 is 53% faster than Opera 9.5 beta, twice as fast as Apple Inc.'s Safari and three times faster than Microsoft Corp.'s IE7 on the SunSpider benchmark, which tests JavaScript performance.

"There are lots of ways to 'game' the system [in benchmarks], but what we're trying to do is speed up the things that enable people to run the really heavy-duty applications on the Web."
Saying that a browser is a browser is a browser when rendering basic Web pages, Schroepfer added that the challenge Mozilla took on was how to build a browser that performs well when asked to run much more complex Web 2.0-esque applications, such as Yahoo's Zimbra, the online collaboration and document suite.
