A lot of people, when they say 'uses a lot of CPU' are leaving off 
'time'. I.e., CPU usage is pretty much talked about in terms of 
cycles, which is roughly utilization*time. Profiling tools often 
report both clock time and cpu time. Cpu time is a rough analog for 
cycles, clock time is self explanatory.
