Information from TOP command

Hello friends,

Could anyone explain to me about the CPU load meaning among LOAD and %CPU?

System: cg02-st1 Wed Aug 18 14:45:00 2010
Load averages: 0.71, 0.70, 0.70

The LOAD average is 55.9% and the process cimserver is using 92.98% .... What is the meaning of each value?

Re: Information from TOP command

>>The LOAD average is 55.9%

No, the USER AVG is 55.9%. That is 55.9% of the CPUs are being used for USER process.

The LOAD, either from the LOAD column or the "Load averages:" line is the average number of processes in the run queue in the interval.

For the "Load averages:" line, the first number is a 1 minute average, the 2nd number a 5 minute average and the 3rd number a 15 minute average.

A perusal of the 'top' man page will give an overview and what the command shows.
