Hey Antoine, Thanks for the link. I'm having trouble getting reproducible results at present, and running out of ideas as to what might be causing it. Even after totally isolating a CPU for e.g. django_v2 and with frequency scaling disabled, numbers still jump around for the same binary by as much as 3%. I could not detect any significant change between runs of the old and new binary that could not be described as noise, given the isolation issues above.
