I wrote: The Linux CFS scheduler prefers pinned tasks and unfairly gives more CPU time to tasks that have set CPU affinity.
I believe I have now solved the problem, simply by setting: for n in /proc/sys/kernel/sched_domain/cpu*/domain0/min_interval; do echo 0 > $n; done for n in /proc/sys/kernel/sched_domain/cpu*/domain0/max_interval; do echo 1 > $n; done I am not sure what the domain1 values would be for (that I see exist on my 4*E5-4627v2 server). So far I do not see any negative effects of using these (extreme?) settings. (Explanation of what these things are meant for, or pointers to documentation, would be appreciated.) --- Thanks for the insightful discussion. (Scary, isn't it?)
