These features address SMP and interactivity and include: +o Thread CPU affinity. +o CPU topology awareness, including for hyper-threading. +o Per-CPU run queues. +o Interactivity heuristics that detect interactive applications and schedules them preferentially under high load. The following sysctls are relevant to the operation of sched_ule: kern.sched.name This read-only sysctl reports the name of the active scheduler. The sched_ule scheduler is disabled by default as it is experimental. See the BUGS section for more information.
