Thank you for that. Sadly I am not able to run it because my

Any x86-64 Linux should have _rdtsc() as inline function (or

Okay. As it turns out knowing that doesn't help me, but thank
you for the info. I'm taking this as a sign from heaven that
I should be spending my energies somewhere other than measuring
performance.
Did you see correction of James Kuyper?
Under Linux it is called __rdtsc().
