Browser : Google Chrome 3.0.192.0 is faster than Safari 4.0.2 (5530.19)

I'm using SunSpider Java Benchmark (http://www2.webkit.org/perf/sunspider-0.9/sunspider.html) for this testing. The result shows that Google Chrome (total run time : 903.0 ms) is faster than Safari (total run time : 1151.0ms) in most area of testing, but in some areas Chrome is also much slower. Chrome is slower in bitops, date and string maniplation.

For example :

1.60x as fast means Chrome is faster than Safari about 60% in 3d testing--3d cude (79% faster)

and 3d morph (90% faster).
