I had posted a "request for information" a few days ago regarding the
interpretation of the perfmeter (OW 3.0) on a SUN MP. I have received
several answers and I thank all the folks who took the time to write to
The correct answer seems to be that the perfmeter shows the TOTAL system
CPU usage for a MP - i.e. for a 2-processor machine, it will show a
utilization of 50% when one processor is pegged out and the other is idle
(or it will show 100% only when both processors are pegged out). I received
an excellent suggestion about using the perfmeter to visually check the
load across 2 processors - run the perfmeter with the following argument:
perfmeter -C cpu 50
This will display the load on each processor in a different color.
Once again, thank you for your responses.
