PREEMPT_VOLUNTARY — Voluntary kernel preemption (desktop)


This option reduces the latency of the kernel by adding more "explicit preemption points" to the kernel code. These new preemption points have been selected to reduce the maximum latency of rescheduling, which provides faster response to applications at the cost of slighly lower throughput.

This option speeds up reaction to interactive events by allowing a low-priority process to voluntarily preempt itself even if it is in kernel mode executing a system call. This allows applications to appear to run more smoothly even when the system is under load.

Select this if you are building a kernel for a desktop system.
