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

[Jon Watte (ODE)]

My first instinct would be to bake the collision of all static things 
into a single static mesh (or a few, block-sized, static meshes).

Another thing you can do is to add profiling code to count how many 
near-callbacks you get, and store information about what attempts to 
collide with what, and plot that. That should show you some spikes.

Characters and other complex systems should probably be in their own 
spaces (spaces can be hierarchical), so that they can be quickly culled 
when not colliding with other entities.

Last, I would absolutely use a profiler to figure out where the most of 
the time is being spent. That would also guide me into making whatever 
optimizations necessary.

Cheers,
