Hi yuanhan,
i understand this email as a 16% drop in hackbench performance when
the number of group is half the number of CPUs. Is it the only test
for which you have seen some decreases ? where can i find the list of
tests that you have passed ?
I'm going to try to reproduce the test in my local setup
Regards,
Vincent
