Thanks for prompt confirmation of the performance change.

This is a new feature released in 10.1 and apparently it (the second parameter
of /run/evenyModulo command) was slipped out from updating our document. We will
fix it by the next release, but meanwhile please refer to the real-time help
of this command if your application runs in interactive mode or this inline
comment.

Tomorrow, we will release 10.2-beta that includes some performance
improvements of General Particle Source in multithreaded mode, which is now the top cpu-eater of your application. Given it is a beta release that is not
supposed to be used for mass production, I would suggest you to try it.
