how to using bullet in serverEnd？

[wdl7770016]

I now want to do a mmorpg
I want to divide my world into many grid
but I must using the physic calculate to make my game more interesting
so I thought:
1.if I using a btDiscreteDynamicWorld to cotain all the obj in the world
it must be very slow because of thousands of obj may collide each other
2.if each grid area I using a btDiscreteDynamicWorld class
there may also be much world objcet
I Think it may also be very waste memory
3.there must be any other method to do for a mmorpg, right？
please give me some advice
thanks...

Try your question in the "General Bullet Physics ..." area, you'll probably get a better response.
