Tuning CPU resources

Process scheduling

In a single processor UNIX operating system, the scheduler only concerns itself with when to run a process on the CPU. In a multiprocessor UNIX operating system, the scheduler not only has to consider when to run a process, but also where to run it. Because the kernel runs on all the processors, the process scheduler may be active on any or all of the CPUs. You can adjust how the process scheduler works in order to improve performance as described in ``Adjusting the scheduling of processes''.
