CPU time reconginzes the distinctuion between WallClockTime and the time the CPU is actually doing calculations. CPU time is computing, not including the time waiting for I/O or other running programs. We kjnow that ResponseTime <> CpuTime!
CPU time can be further divided into:
- system time - Time spent doing OS work
- user time - Time spent executing user program
