SYNOPSIS
.Cd "options SCHED_ULE"
DESCRIPTION
The sched_ule scheduler is an experimental scheduler that provides a number of advanced scheduler features not present in sched_4bsd(4), the default system scheduler. These features address SMP and interactivity and include: - Thread CPU affinity.
- CPU topology awareness, including for hyper-threading.
- Per-CPU run queues.
- 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.
