So for SLE the consensus is to keep CONFIG_HZ=250.

I assume you mean SLE15 here? I think the discussion should be open ended with SLE16.

Cyril recommended to keep CONFIG_HZ=250 citing the bug fixed by commit c7fcb99877f9 and Mel recommended to keep SLE and ALP aligned which implies CONFIG_HZ=250 for ALP as well.

I'm sorry, but that means there can be no progress of anything anywhere ever. But the matter of fact is that we are improving the config continuously based on feedback.

So I agree we should revert the change. Objections?

Well, what about the original suggestion to use a value that is evenly divisible for the user space metrics? I checked again, and RHEL9/10 is going with 100 HZ. So if your concern is that the number of tick interrupts is causing performance issues, why not go to the *same* value across all architectures, and pick a value that is evenly divisible by 100 (the userspace HZ)? Like 100? (or 300, for that matter) I picked 300 because it was closest to the original 250 which I thought is the least concern overall. There were no conclusive benchmarks showing it would be a problem. Why can we not run with that to see partner and customer feedback prior release? -- You are receiving this mail because: You are on the CC list for the bug.
