Interesting... OS X 10.9 - Chrome 30.0.1599.101: 21264 - FF 25: 15911 - Safari 7.0 (9537.71): 14438

  It's interesting to me that OS X builds of Chrome and Firefox seem to show a bigger performance gap than Linux/Windows builds do. I wonder if any of the tests are dependent on platform-specific features like Canvas or WebGL? It seems like they shouldn't be...

    There are real plaform differences in the way the browser interacts with the OS. Significant differences aren't inconceivable - it's not just stuff like GFX, there's also threading, power saving, async, I/O, memory, caching - I've no idea what's going on here, but it's definitely possible. Also, is it possible some of these browsers are running as x64 on macosX? Because on windows, I'm pretty sure chrome and FF don't.

      > Also, is it possible some of these browsers are running as x64 on macosX? The OS X task manager lists Safari and FF as 64 bit, Chrome is 32 bit. I'm also seeing the same dramatic performance gap. Chrome is at 23k, whereas Safari and Firefox come in just under 16k.
