For comparison same setup with Firefox 4 Beta 6 got 17568.9ms +/- 0.3%

Setup:
Windows 7 64-bit
Intel Core 2 Duo E8400 @ 3.00GHz
4.00 GB RAM
Intel SSD 80GB G2

I just ran the new Kraken benchmark released by Mozilla, result 48979.0ms +/- 2.8%.

Laugh all you want but I have had it running on IE 8 (Windows 7 64 bit) for the past 5 minutes and it is still stuck at the first stage. So I think we have a legitimate reason why Internet Explorer was not included...

Also got a warning that "A script on this page is causing your web browser to run slowly."...
