still don't understand you.
CPU will not perform the same at 10% utilization, it will perform 10 times
less than at 100% utilization.
CPU load == CPU utilization == how big percentage of time CPU (or CPUs by
average) are doing anything except being in idle loop or hlt/waiting for
it's exactly the same words in that context.
load average is how much processes (by average) is not doing calculations
because something is not yet available and depends of computer
resources(*) - like CPU time, disk I/O results etc..
(*) - for example waiting on tty read is not calculated to load average as
it's depends on human not computer.
