[ODE] Slow performence in a given scene - optimizable, or "just how it is"?

[Szabo Gabor]

Hi,

It's interesting: "condensing it into a static trimesh". A question, 
that maybe already exists: when is it better to use trimesh geoms 
instead of composite geometry (or vica versa)? Is it enough to compare 
the summary of the polygon number in the resulting object? I don't think 
so, and the answer could be is very useful. I think it depends on the 
solver (world, fast, quick), the geom types in the object, but are there 
any formula to calculate with to setup the more effective physic 
geometry structure (trimesh vs geoms)? Or do I have to test each case?

Thank you,
