Depending on repeatedly pulling the wakee back to the same node as the waker suggests something else in the kernel may be pulling the wakee to another place in the system repeatedly, as well, just at a lower frequency (load balancer?). I have also noticed that select_idle_sibling often fails to find an idle sibling within the LLC domain, even when it exists. Fixing that bug sometimes results in lower performance. It appears that some of the performance results of the scheduler appear on the code acting in an opposite way to its documented intention. It may be best to revert 096aa33863a for now... > b1ad065e65f5610 096aa33863a5e48de52d2ff30 testbox/testcase/testparams > --------------- ------------------------- --------------------------- > 1312 ±
