Thank you very much Eugen, this will be interesting.

As for deactivating InsertionSortCollider, it is easy (collider.dead=True). It means stopping contact detection, though... Not really possible unless you really have to simulate a fixed network of interactions.
What would make sense would be to implement another collider that would use parallelism, then it would be possible to choose between different colliders depending on the available cores and the size of the problem.

We have different colliders already in fact (see ZECollider) but they
are all single-threaded and InsertionSortCollider is so fast that it is
not worth mentioning the others at this point.

What is the typical cpu time spent in collider in your tests?
