My guess is that most people who hit a performance wall with canvas are using overly complex vector graphics and not caching bitmaps as often as they could. While things like OpenVG are on the horizon, vector drawing is still a CPU-bound activity most of the time, while bitmap blitting is all GPU. This is the case whether you're using canvas or a native graphics library.
