In September, Firefox backer Mozilla countered Google's benchmark suite, spotlighting Firefox's superior results using the SunSpider speed test. Here, TraceMonkey works, and Firefox maintains its lead over Chrome and the others.
I couldn't run SunSpider when Chrome was released because the site was out of commission that day, but it's up and running again now, so here's the latest results for the four browsers--and bear in mind here that a smaller score is best for SunSpider: TraceMonkey-enabled Firefox led with a score of 2,257; Chrome was second at 2,904; Firefox 3.1 beta 1 with no TraceMonkey next with 4,233; Safari 3.1.2 followed at 6,351; and IE 8 beta brought up the rear with 9,025.
