    I am loading many small balls in a cup. However, CPU usage can be very high when number of balls is larger than 100. Ball is with a rigidbody and a sphere collider and is child object of cup. But CPU usage is normal when balls out of cup. Why does it happen?

    I think this happens because in the cup there are a lot of contacts and it take some time to run all simulations to resolve all collisions. Perhaps someone in Physics forum can help
