[SunHELP] what do CPU utilization figures actually measure

I would have thought that CPU utilization measure the time the CPU was
active.  I've been told by a couple of sources that CPU utilization is a
combination of wait for I/O, CPU usage and something else.

Can anyone tell me what CPU utilization actually represents on a Solaris
system.  If I remember correctly from my mainframe days i/o waits were not
considered part of CPU utilization.  

Many thanks
