Thanks for your answer.

When it comes to 8, the timing changes randomly, sometime times is less
than the time needed to solve 80 equations. I did 4 runs again, the times
were between 115000 and 125000. This program is very simple and each and
every thread does the very same thing using the very same code, no
difference between the threads. I do know how to debug that further. The
 main thread just sends the pointer and the worker thread solves it after
receiving it, 3 lines are relevant.The thread is a basic windows thread
like in inproc_lat.
