Question #244277 on Yade changed:
https://answers.launchpad.net/yade/+question/244277

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Klaus,
what kind of simulations do you use? some simple one or large? I can
imagine one possible reason for large simulations - 16 concurent
simulations exceed RAM forcing the program to HDD swapping and therefore
slowing the simulation, which would not ocure in single simulation.
cheers
Jan
