[Opensim-dev] object memory footprint for ODE

[Nebadon Izumi]

its not that simple, it depends on the complexity of your meshing, what
shapes you chose etc.. a box wont use the same amount of memory as a torus
thats cut twisted and hollowed out.   Also sculpty prims tend to use a bit
more memory than standard prims,  its almost impossible to predict what
memory it will use at this point, but chances are with 1gb ram you will be
able to run 1 sim with 15k prims. all depends, if your running linux likely
1gb is not even enough ram to run 1 full 15k prim sim.. on the other hand in
windows you could likely run 1 sim with 15k prims and have some memory to
spare.. there are just to many variables in the equation though to predict
accuratly.   and again, our stats are server side, cuda wont do you any
good, its likely opensim will never be able to use video card accelerated
physics, its just not possible short of re-writting the linden viewer from
scratch and redoing opensim 100% also.
