    Subject[PATCH 0/1] Improve yield (was: sched: Move SCHED_DEBUG sysctl to debugfs)
    Date
    I did a reduced testcase and assuming that the reduced testcase has the
    same issue, it turns out that a lower sched_migration_cost_ns does not
    solve a specific problem, instead it seems to make a different problem
    less problematic. In the end the problem seemed to be worse on KVM hosts
    (guest changes did also help but much less so). In the end what did help
    was to improve the behaviour of yield_to from KVM.
    See the patch for more details. The problem seems to be real, my
    solution might not be the best one - I am open for better ways to
    code things.
