Bunny test

Has anybody created a Bunny test?
Meaning a stress test to see how many moving and rotating sprites can be displayed at once.

I have created one with CCSprite but FPS would drop at about 5k :confused: I am obviously doing something wrong, since the same test with Flash goes up to almost 250k.
Actually FPS drops at 5k even if they are not moving, which is kinda odd…
