hi, Raghu,
hope this third performance report for same one patch-set won't annoy you,
and better, have some value to you.
Not at all. But thanks a lot and am rather more happy to see this
exhaustive results.
Because: It is easy to show see that patchset is increasing readability
of code or maintainance of code etc.,
while I try my best to see regressions are within noise level for some
corner cases and some benchmarks have improved noticeably, there is
always a room to miss something.
Reports like this, helps to boost confidence on patchset.
Also your cumulative (bisection) report also helped to evaluate
importance of each patch too..
we won't send more autonuma-benchmark performance improvement reports for this
patch-set, of course, unless you still hope we do.
BTW, we will still send out performance/function regression reports if any.
as in previous reports, we know that you want to see the performance impact
of whole patch set, so let me give a full summary here:
let me list how we apply your patch set again:
68cfe9439a1ba (linux-review/Raghavendra-K-T/sched-numa-Move-up-the-access-pid-reset-logic/20230829-141007) sched/numa: Allow scanning of shared VMAs
af46f3c9ca2d1 sched/numa: Allow recently accessed VMAs to be scanned <-- we reported [1]

fc769221b2306 sched/numa: Remove unconditional scan logic using mm numa_scan_seq

2a806eab1c2e1 sched/numa: Move up the access pid reset logic

below will only give out the comparison between 2f88c8e802c8b and 68cfe9439a1ba
in a summary way, if you want detail data for more commits, or more comparison
data, please let me know. Thanks!

Hello,
