Jitter is massively inefficient when not running single-threaded

[nuclearpidgeon]

Potentially solvable through a better implementation of the Task/Queue setup implemented with Ryan Crosby (friend who is a C# dev)

[lberezy]

Proposed workaround is to configure the physics system to do as few iterations as possible, use single threaded mode and use an appropriate broad phase culling algorithm (SAP, not brute force which is O(n^2)). (http://jitter-physics.com/wordpress/?tag=broadphase)

All of this is configurable in PhysiscsSystem.cs
