[ODE] performance problems when bodies lean on each other

[Hampus Soderstrom]

Hi,

I'm experiencing slowdown of my application when two or more bodies  
rest on top of each other creating constant collisions?

Every frame i get about 180 calls to nearCallback and 15 of those  
result in a contact point. I'm using HashSpace, dSpaceCollide and  
dWorldStep.

Should this be slow or can I tweak my engine to handle bodies leaning  
on each other better?

cheers
