But it is not: See: http://en.wikipedia.org/wiki/Load_average A high load average should have your CPUs running near 100%; if they are not, on some platforms that tends to indicate that many processes are (or would be) runnable but are being blocked in a short-term wait condition due to network or disk I/O, or are being affected by VM paging activity. This line of your top output indicates many processes are in a WAIT condition: > 514 processes: 3 running, 490 sleeping, 1 zombie, 20 waiting Regards, -- -Chuck
