Hi Oliver!
Thank you for testing it!
Btw, can you, please, confirm that the regression is coming specifically from ace7e70901 ("percpu: use reclaim threshold instead of running for every page")? I do see *some* regression in my setup, but the data is very noisy, so I'm not sure I can confirm it.
Thanks!
