Number of processes in the run queue, averaged over time. Often confused with CPU utilization, which it is not. At load >= 1, CPU utilization is nominally 100% -- for a 1 CPU box. For an SMP box, eg: the 14-way Sun E10K I worked on a while back, a load average of 7 was 50% utilization. The fourth value is running processes vs. total threads, and the fifth value is the most recently assigned process ID.

A system with a load average some higher than the number of CPUs present will probably benefit from additional CPU(s). Sustained loads more than, say, 4-5 times CPUs indicated a pretty saturated system. 7:19pm up 33 days, 17:29, 17 users, load average: 2.00, 2.03, 2.14 -- Karsten M.
