So I run all my installed browsers with my Centrino 2 cpu, win7sp1x64 and here are my results, run with my hardware.
|Internet Explorer 9.0.8112.16421||220ms|
|Internet Explorer 10 platform preview 2.10.1008.16421)||234ms|
|Firefox 11 beta||250ms|
|Opera 11.61 (build 1250)||255ms|
|Safari 5.1 (7534.50)||257ms|
|Chrome 17.0.963.46 beta-m||277ms|
As you can see, the results are very similar these days. So if you have an up-to-date browser, your fine.

And if someone is still using IE6 or 7, please upgrade a.s.a.p. check out the kill bill’s browser website if you are not convinced.
Enjoy your browser!
