Comment 18 for bug 729079

Hi Bruno,

there is a comparison of new and old collider.
A newer one is slower, but it can be because of
tons of warnings like this:

931937 ERROR yade.InteractionContainer /home/gladk/dem/yade/cleanCompBruno/yade/core/InteractionContainer.cpp:55 erase: InteractionContainer::erase: attempt to delete non-existent interaction ##14889+15066

It can be related to the bug 813925 [1]

The script, what I used, creates and removes bodies very actively.

Speed, iter/sec
-j Old collider New_Collider:
1 7.94 6.12
2 13.85 11.4
3 14.83 14.2
