In the past, I had bad surprised when running benchmarks without PGO:

I don't recall if ALSR was enabled or not. But I don't think that I
used multiple processes when I ran these benchmarks because I didn't
write the code yet :-)

I should probably redo the same benchmark using new shiny benchmarking
tools (which are expected to be more reliable and stable).
