Yeah, on my MacBook Pro (OS X 10.6, Core i5 2.4GHz) I got

  Safari 5               11018.2ms +/- 0.3%
  Chrome 6.0.472.55      15342.7ms +/- 1.0%
  Firefox 3.6.8          18917.6ms +/- 0.1%

Interesting (but maybe not surprising) to see that Safari is consistently being reported as faster than Chrome on OS X, but not on Windows.
