If that was your goal then the information you learned may be helpful to us.
Could you describe your setup in greater detail? Some things that may affect
the outcome would be:
* how many scripts were running in each region
* which physics engine you were using
* which meshing option you were using
* how complex the prims were, i.e., were they simple boxes or spheres, or
were they more complex prims such as torii, rings, or tubes with twists,
hollows and profile cuts?
* anything else that you've noticed has an effect on cpu or memory
utilization
Thanks,
-D
