I know you’re wondering how much better it performs, and so I’ll turn your attention to the Sunspider test, which we’ve used in the past to compare the various browsers. I ran all of the following tests on the same MacBook Pro computer with the Mac OS X operating system (lower amount of time is better):
- Safari 3.1.2: 3062.0ms
- Firefox 3.0: 2997.2ms
- Firefox 3.1 nightly without TraceMonkey: 2510.2ms
- Firefox 3.1 nightly with TraceMonkey: 1610.4ms
That’s a rather significant difference. Compared to Firefox 3.0 the new Firefox 3.1 nightly build is nearly twice as fast, and my results are consistent with those that Mozilla got. Bravo!
There’s still some work that needs to be done on TraceMonkey, and some bugs need to be ironed out before it will be ready for prime-time. I’m already getting pumped about Firefox 3.1 though.
