Try put this in /etc/sysctl.conf or /etc/sysctl.d/ Code: kernel.sched_features=21 kernel.sched_batch_wakeup_granularity_ns=25000000 kernel.sched_min_granularity_ns=4000000 and then run sysctl -p These options are not available unless "Kernel debugging" (CONFIG_DEBUG_KERNEL) and "Collect sheduler debugging info" (CONFIG_SCHED_DEBUG) in "Kernel hacking" are enabled so you most likely need to recompile.
