# SCHED_ULE is a new scheduler that has been designed for SMP and has some
# advantages for UP as well. It is intended to replace the 4BSD scheduler
# over time. NOTE: SCHED_ULE is currently considered experimental and is
# not recommended for production use at this time.
# SCHED_ULE provides significant performance advantages over 4BSD on many
# workloads on SMP machines. It supports cpu-affinity, per-cpu runqueues
# and scheduler locks. It also has a stronger notion of interactivity
# which leads to better responsiveness even on uniprocessor machines. This
# will eventually become the default scheduler.
