Dramatically reduce the CPU usage of 'top'
Authored by: jschank on Feb 20, '04 12:42:31PM

I thought I'd check Activity Monitor to see if it was as bad. Apparently, Activity Monitor performs better than the default top, but worse than the optimized call being discussed here. Perhaps folks would be interested in using AM instead of top?

I'd alwas thought, as a previous poster noted, that top overreports itself because it's active when it's looking for active processes. So does ActivityMonitor.

Interestingly, however, AM shows top above the 10% level, but top shows AM at about half that. Moreover, top and AM basically agree on their own and each other's usage.
