I have done some tests on 6-core machine, and I can confirm again, that it is almost impossible to operate with more than 10^5 particles. The calculation speed is very slow and cores are not completely loaded. Timings show, if more particle we have, insertionsortcollider takes more calculation time, see table in %:
