# Javascript Performance: Google Chrome, Firefox & Safari

Today I've been playing with Google's new web browser,
[Google Chrome](http://www.google.com/chrome/). So far I have to admit I'm very
impressed. Specially about the new JavaScript engine called V8, as it even
leaves [WebKit](http://webkit.org/)'s new
[SquirrelFish](http://webkit.org/blog/189/announcing-squirrelfish/) JS engine
eating dust.

Here's the results from my most likely very-unscientific JS performance tests
using [Dromaeo](http://dromaeo.com/) (dead link). All tests were done within
minutes of each other, during equal system loads on a 1.8 GHz Core 2 Duo machine
running XP SP2 (work machine, as I only have Macs myself).

Google Chrome registers as "Safari/525.13" since they both use the WebKit
rendering engine.

Best Dromaeo results I've seen with Google Chrome is 180ms on a friend's 2.66
GHz Core 2 Quad system.

P.S. Yes, that chart was created using MS Office, rather than Keynote or
something, as my MacBook Pro is still in the UK getting repaired. But more on
that later :P
