They are both correct for what they are trying to show. One is average over a small piece of time, the other is an average over a much longer period. They will never align. You are both right. This is why windows gives a chart updated every 1 second for windows task manager. unix top is similar and updates frequently to give a more accurate picture of what is going on. Inferring usage over a longer period of time from a one time snapshot doesn't give the bigger picture, nor taking an average over several minutes isn't realistic either for what is going on "now" or "recently". A chart updated frequently gives a better picture. The source of the data and how it is calculated is the same: averages over 1 second plotted every second (or there about). Having live charts for some of this stuff would be more useful than static snapshots. Both queries are using windows performance counters via wmic. There is no other source of the data. There more direct ways to get the data than going through wmic, but the origin is the same.
