V8 Javascript Benchmark
http://v8.googlecode.com/svn/data/benchmarks/v4/run.html
A benchmark to test Javascript performance. Widely believed to be heavily skewed in favor of Chrome. Larger scores are better.
Chrome 2377
Safari 1683
Firefox 3.5 RC1 279
Opera 182
Firefox 3.0.11 166
IE 71.3
Conclusion
Firefox 3.5 RC 1 feels much faster than the previous versions, and is catching up to Chrome. However, it is still about 2x slower than Chrome according to the SunSpider benchmarks.
