Hi, Mel Gorman, we reported "[sched/numa] bb2dee337b: unixbench.score -11.2% regression" last month at https://lore.kernel.org/all/20220518092414.GA15472@xsang-OptiPlex-9020/ and according to your inputs and experiments from Ying, we got the idea this commit could benefit some workloads but cause regression on others. now we noticed this commit in tip now, and we found another regression in one PTS test (the fsmark regression reported in bb2dee337b report is also reproduced). just FYI Greeting, FYI, we noticed a -8.0% regression of phoronix-test-suite.vpxenc.Speed5.frames_per_second due to commit: commit: cb29a5c19d2d68afc641fb1949e1a1c565b582ea ("sched/numa: Apply imbalance limitations consistently") https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git sched/core in testcase:
