No load average is not just CPU but reflects all parameters. For pure
CPU usage system monitor or similar tool will give better
understanding. Also the processes (or dameons) running will really
determine the expected load average.
But as some else said for genera usage 2~3 times x number of
processors is a thumb rule guide.
