How many people raytrace, crunch fractals or do 3d in Javascript on their mobile devices? Sure, this helps, but it's avoiding the main problem and perception of slowness in browsers for the vast majority of users: rendering speed. It's not how fast the javascript is that's important, the majority of time is taken up reflowing, redrawing and composing the page after the Javascript has modified the DOM. And the much promised speedups in Cairo don't seem to be materializing. This is great, but when was Javascript performance ever the bottleneck?
