[ILUG] System load explained.

[Walter Faleiro]

Hi Belgarath,
I used top to get the load average too, and sometimes it shows processes
eating 99.9 % of cpu time. But how do I confirm that there is no I/O
operations involved here. Does load average give only cpu and memory
consumption? Also can't the memory consumption be because of high I/O?

Thanks,
--Walter
