20% sounds good, but unless versions 5, 6 and 7 also had 20% improvements, it would still be slower than the current version of Chrome on canvas stuff. For the relatively simple canvas rendering I'm doing, I can watch Firefox chugging along at 10fps struggling to render a few dozen filled rectangles, while Chrome is happily pegged at 60fps (via RequestAnimationFrame). It's just night and day.

Wow, that's not what I've experienced at all. Please post links to your example.

Canvas on Firefox is hardware accelerated (at least on Windows), so it's really fast. I don't have Chrome installed, but I'm pretty sure it chokes on the FishIETank benchmark with 1000 fish: http://ie.microsoft.com/testdrive/Performance/FishIETank/Default.html http://ie.microsoft.com/testdrive/Performance/FishIETank/Def.... Firefox on the other hand easily gets 60 fps with those many fish.

  Excellent example. On my system, Chrome12 will do 100 fish at 25-30 FPS, while FF5 chugs along at 7-10fps. Neither is particularly good, but the Chrome one is at least watchable.

    That just means your Firefox isn't benefiting from GPU acceleration. It could either be because your OS or hardware doesn't support it or because your graphics drivers are out of date.

      The reason why is unimportant. The end result is the same: terrible performance on Firefox, good performance on Chrome. It's not up to the end user to know or care why.

        Terrible on YOUR machine. On something like 45% (and increasing) of vista or win7 machines the story is the opposite.

> It's just night and day. It's mostly night and day in the opposite direction. Firefox 4+, like IE9+, uses Direct2D on Windows. That leads to canvas being much faster than Chrome (if your graphics card supports that). On other platforms, results may differ, and it depends on your graphics card. I am guessing that you happen to have a configuration that Chrome runs better on, but most benchmarkers have found (as expected) than Firefox and IE have faster Canvas implementations than Chrome (since they tested on Windows, with cards that can utilize Direct2D).
