Hope this helps
I agree, anything JS is much faster in Chrome compared with other browsers
... except ...
... FF4 Beta 1. The new FF JS engine is very, very quick. Opera isn't too bad also
Actually I have yet to try FF4, but for what I can gather around the different browsers, the next generation of browsers is going to put to shame everything we've known until 2010, even IE9 looks promising.
Although i digress
