Very interesting feedback!
It will be difficult to say something without a working script and without specific timings, though.
I thus have questions, only. :)

May I ask:
- "faster": just to be sure, you are speaking of real wall clock  time per numerical time iteration, correct? Are timesteps the same?
- "more than 2000", what does it mean? 2500? one million?
- do you have an approximately linear time vs. Nparticles?
- "verletDist=rball*2", why?
- would you share more of the data?
- could you report timing.stats() [1]?
- could you show a working script?
