Two main bottlenecks could be: a) "physics", b) collision.

Why that much? :) If the bottleneck is "physics", first try to reduce
iterations (say, to 2) and see if that helps. Also, maybe you could go with a
larger timestep (and tune ERP/CFM parameters a lot to get good simulation).
If the bottleneck is collision, then make sure you don't collide ragdoll
parts with itself; and use some space to keep the ragdolls (which one -
depends on, umm, lots of factors :)).
In any case, the first thing would be to profile it and see what's happening.
