Hi Preeti,
Other numbers that would be interesting to know are the % improvements
when N = 20. That is when I'm getting the bigger performance boosts on
some of the AIM7 workloads.
Would you like to re-run ebizzy with v2 of my patch except replacing
this line of code:
if (idle_duration / 10 < (sd->avg_idle_balance_cost + cost))
with this line of code:
if (idle_duration / 20 < (sd->avg_idle_balance_cost + cost))
Thanks a lot,
Jason
