Same site: six seconds in Chrome Beta, nine in IE8, and thirteen in Maxthon. I don't have FireFox.

And yes, it's another Beta - they've got the standard release, and a Beta release which contains new features, is quite a bit faster, but is considered unstable. When they've got the beta sorted, then it becomes the standard release and they release another beta with more new features, but which is unstable.

Safari 4 for Windows is apparently pretty quick, which is a surprise. Makes you wonder if they've started using the version of WebKit that Google has optimised for Chrome.
