I searched around and found some interesting things for Firefox. From the following two Tinderbox page, Firefox 3.0 performance has been improved to compare with Firefox 2.0: http://tinderbox.mozilla.org/showbuilds.cgi?tree=Firefox http://tinderbox.mozilla.org/showbuilds.cgi?tree=Mozilla1.8 Please note the two trees named "Linux talos trunk fast qm-plinux-fast01" and "Linux talos branch fast qm-plinux-fast02". They run on two mac minis with same hardware configuration, deploy the talos[1] test framework with automation testing[2] for Javascript, DHTML performance, Startup time, Page load time... I also tried the sunspider benchmark: http://webkit.org/perf/sunspider-0.9/sunspider.html on my x86 box here(Nevada b87 with Firefox 3.0b5 and 2.0.0.12) and saw some improvement for Firefox 3.0. BTW, some performance/memory footprint progress for Firefox 3.0 on Solaris(Thanks for Ginn's hard work): https://bugzilla.mozilla.org/show_bug.cgi?id=425626 https://bugzilla.mozilla.org/show_bug.cgi?id=422055 Cheers, -Alfred [1] http://quality.mozilla.org/projects/automation/talos [2] http://wiki.mozilla.org/Performance:Tinderbox_Tests
