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

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.
Thank you.
I'd guess I knew it once, but because I don't run microbenchmark on
Linux all that often, had forgotten.
