Profiler clarifications and help

Hi all,

I am trying to profile for iPhone 4, and I'm getting pretty poor performance. I am using SpriteManager2, and my game is pseudo-2D. I'm sitting at around 25 draw calls, which I'm finding hard to reduce due to the complexity of the scene.

The culprits in my profiler are: Drawing 20% Culling 20% Animation.Sample 15%

I get the drawing part, I'm using lots of alpha blended objects, but how am I getting all this culling and animation sampling? Where do these get triggered, and how can I optimize them?

Any clues would be appreciated, thanks!!
