Firefox 3 Performance Boosted

Cybernet News posted an article on Firefox 3 performance showing results of the SunSpider JavaScript Benchmark test for each of the different browsers. They conclude that Firefox 3 is now faster than Safari 3, and is close to WebKit nightly in certain benchmarks.

 

A Profile-Guided Optimization (PGO) build of Firefox 3 had been created which greatly improved the performance of JavaScript in the browser. While PGO itself hasn’t yet landed in the nightly builds there have been some significant improvements to the JavaScript engine.

All of the tests below were performed on the same Windows machine, and the Firefox 3 nightly builds definitely came out on top. Here are the results sorted from best to worst (each one is hyperlinked to the full stats):

1. Firefox 3 Nightly (PGO Optimized): 7263.8ms
2. Firefox 3 Nightly (02/25/2008 build): 8219.4ms
3. Opera 9.5.9807 Beta: 10824.0ms
4. Firefox 3 Beta 3: 16080.6ms
5. Safari 3.0.4 Beta: 18012.6ms
6. Firefox 2.0.0.12: 29376.4ms
7. Internet Explorer 7: 72375.0ms

Firefox 3 Beta 4 is expected to be released in the next few weeks includeing these and many more improvements.
