I maybe wrong, sorry, never coded on "clumps".
But, it seems, the bottleneck is the loop in lines 159-177 [1].

Why do we need to discretize the cell? Is it possible just to go through all
spheres and to summ m*r^2 of each sphere?

Title:
  Loading clumps takes too much time

Status in Yet Another Dynamic Engine:
  In Progress

Bug description:
  The examples/packs/packs.py hangs in line 46 [1] because
  of appendClumped command.

  Changing it to "append" fixes the problem. So, it seems, 
  appendClump has infinite loop  somewhere.
