Thanks Helio. So it's not just me.

Since the mathematics behind Mahalanobis indicate a linear dependency between the observation count and the execution time, I'm simply going to ignore this time-jump.

Thanks for all the help.

Regards
Chris

As you can see the time-jump also happens here. Note the high 1st run times on OpenSUSE.

I've attached a small example program (with a makefile) that does the test. I'm using gettimeofday, which will probably only work under Linux. It might take a couple of seconds to execute. I would apprciate it if someone could run it (sorry Allin, this is probably the wrong mailing list again for posting C code), and verify that I'm not the only one with this time-jump.

These are my outputs:

197 number of observations: 784814
198 number of observations: 760379
199 number of observations: 759822
