The "load" is the number of active processes (the number of processes in the run
queue). That's all it measures - not CPU load, disk I/O or anything else -
purely the number of processes in the run queue.
Load and processor usage aren't linked. If the processes are I/O bound (for
example) then while the system load may be high, the actual CPU usage may well
Google produced http://www.teamquest.com/resources/gunther/ldavg1.shtml, which
isn't a bad description of the load average, though heavily based on Linux.
