Dramatically reduce the CPU usage of 'top'
Authored by: avarame on Feb 21, '04 05:23:30PM

I just ran two copies of top, and compared their monitoring of each other. One was the modified version mentioned here, the other was plain-jane /usr/bin/top. /usr/bin/top and 'ttop' agreed within a couple of percent on CPU usage by /usr/bin/top. The differences went both positive and negative (that is, there was no bias by either copy of top in either direction).

In any case, average top CPU usage has gone down from 15-20% to 2-5% on a 700Mhz G3! Thanks so much!!
