 Robert Love Explains Variable HZ

Robert Love provides details at KernelTrap on a recent patch he's backported from the 2.5 development kernel to the 2.4 stable kernel. The patch allows one to adjust the frequency of the timer interrupt, defined in 2.4 with "HZ=100". Robert explains, "The timer interrupt is at the heart of the system. Everything lives and dies based on it. Its period is basically the granularity of the system: timers hit on 10ms intervals, timeslices come due at 10ms intervals, etc."
