Browser-JavaScript Performance on Mac OS X

JavaScript performance is one of the most important things in recent browser development.

Google did an awesome job with Chrome’s V8, and Mozilla’s Tracemonkey also raises the bar.

I usually compare the performance on this site

The tests were done on a MacBook Pro (2007), here the results:

Firefox 3.0.1 on Mac OS X

Firefox 3.1 Alpha (2008-09-29 nightly) on Mac OS X

Webkit (2008-09-29 nightly) on Mac OS X

Google Chrome running on top of Mac OS X in Parallels with Windows XP SP3

Note how fast Chrome is – even when running on top of two operating systems!

Opera 9.5 running on Mac OS X
