Markus, and anyone else wondering about interactive performance regressions, NEW_FAIR_SLEEPERS is modifiable at run time; just run
echo NEW_FAIR_SLEEPERS | sudo tee /sys/kernel/debug/sched_features grep --color=tty NEW_FAIR_SLEEPERS /sys/kernel/debug/sched_features (Ubuntu mounts linux's debugfs at /sys/kernel/debug, not at /debug like you see referenced on the lkml threads talking about this.) To enable for every reboot, put echo NEW_FAIR_SLEEPERS > /sys/kernel/debug/sched_features in /etc/rc.local, or whatever. -- Consider disabling NEW_FAIR_SLEEPERS https://bugs.launchpad.net/bugs/436342 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
