Investigating the Performance of Firefox 4 and IE9

Posted by Soulskill on from the nine-is-bigger-than-four-so-it's-better-right dept.

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).'"

    Benchmarks that Microsoft use are inherently favoring Microsoft and benchmarks that Mozilla use are inherently favoring Mozilla. That's surprising isn't it?

    At least I commend the investigative work done here and the fixes applied to FF4. I hope we can see those before the final release!

    My benchmark is pretty simple: Can I plan Entanglement without the fan spinning up? IE9 and Chrome don't spin the fan up, FF4 does.
