Hello,
During performance testing, we found a regression of ~9% performance
with the TPCC benchmark. This performance regression was introduced in
v6.6-rc1. After a bisect, the following commit was identified as the
cause of the regression:
86bfbb7ce4f6 ("sched/fair: Add lag based placement")
I was hoping to get some feedback from the scheduler folks. Do you
think gathering any additional data will help diagnose this issue? Are
there any tunable options that can changed to see how performance is
affected?
Thanks,
Joe
