Ends up the “HTML5” test was really, really poorly coded. Here’s a version that gets 45 FPS on my iPhone 4. Pays to be skeptical of any claim that Flash Player works well on mobile devices.
Update: Here’s another tweaked version of the canvas demo, this one from Charles Ying, that updates the FPS counter less frequently (to match the Flash version), which performs even better.
