I don't have Arm server to test on but this looks like a serious issue
with Arm performance. FYI the default 1000000 takes 10 seconds on
slow NUC (AMD x86). Is this a problem with the lack of real compare-exchange
and the default atomic retry model for that?

This patch didn't get applied in 3 years but still worth investigating
if anyone has resources.
