ABSTRACT:
A computer implemented method, apparatus, system, and computer usable program product for controlling preemption rates. A scheduler identifies a preemption interval in response to a plurality of processes being executed by a processor. Only a single preemption of a process occurs during the preemption interval. The scheduler preempts a currently running process only once during the preemption interval. The preemption interval is adjusted to increase performance in executing processes.
