sched_4bsd(4), the traditional 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.

- This read-only sysctl reports the name of the active scheduler.
