If the collider takes 6% with 50k spheres, then optimisation should 
focus on interactions handling (but perhaps this really optimised already)

Well, fundamentally, there is no difference, bodies get out of BBs at 
each time step already. With detectionFactor = 1, you can miss contacts 
created DURING the timestep, if spheres are x-aligned.
Just imagine that activating the collider each 10 steps is like setting 
dt 10 times larger...

Just read the abstract and forget it :
"The algorithm is applicable to systems comprising bodies of a similar 
sizes."
