AGG renders everything in software. It uses fixed point math whenever it's 
possible but obviously there are lots of floating point calculations to be 
done. If your CPU lacks a FPU then this will certainly slow rendering.

I don't know what kind of Flash movie you are trying to play and how well it 
performs on your CPU. We try to optimize software rendering but there is no 
much left that can be done to speed up rendering.
