Thank you for that. Sadly I am not able to run it because my
test environment is lacking _rdtsc(), and I haven't been able
to find out how to install it.

Any x86-64 Linux should have _rdtsc() as inline function (or built-in) defined in x86intrin.h. No installation required.

On my x86-64 Linux system, that header (indirectly) declares __rdtsc(),
but not _rdtsc.
