> 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).
