Investigating the Performance of Firefox 4 and IE9

theweatherelectric writes "Mozilla's Robert O'Callahan has investigated the performance differences between Firefox 4 and IE9. He writes, 'As I explained in my last post, Microsoft's PR about "full hardware acceleration" is a myth. But it's true that some graphics benchmarks consistently report better scores for IE9 than for Firefox, so over the last few days I've been looking into that. Below I'll explain the details [of] what I've found about various commonly-cited benchmarks, but the summary is that the performance differences are explained by relatively small bugs in Firefox, bugs in IE9, and bugs in the benchmarks, not due to any major architectural issues in Firefox (as Microsoft would have you believe).'"

Real Benchmarks

[camcorder]

Only benchmark I care is the real usage of web. Is there any benchmark available that tests sites such as top 30 sites listed on alexa.com, and have some automated usage profiles and compare load time, render time, memory usage etc.?

Pick a browser. If that works for you then well done. If you dont like it then pick another.
Politics, morals & fanboi-ism aside none of the browsers are really that bad any more.

NEVER hang the UI

[anethema]

What's stupid is the wrong stuff is being concentrated on.

If google maps loads in 3 or 4 seconds doesn't matter to me. What I want is for the whole browser not to hang its UI anytime one website is doing stuff. I hate opening tabs in the background and having the browser be unusable until they load.

And this is on a quad core i7, 8gb of ram.
