Stress Test CPU Utilization•Total CPU utilization % tells us how busy thesystem is.•Shows the Max and Modal value for TotalCPU utilization.•For this run, Max and Modal Total CPUutilization are both 100%March 2004 Copyright © 2004 HP corporate presentation. All rights reserved. 72
Stress Test CPU Utilization•Priority Queue is seldom greater than 10on customer systems. This indicates aCPU bottleneck.•The field recommends that Total CPU Utilization isbetween 40-60%. If a system regularly exceeds 60%utilization, they recommend considering a hardwareupgrade.•Many customers sampled do experience 100%Total CPU Utilization periodically, but the averageand modal values on these systems are significantlylower than 100%.•CPU System Mode Utilization seldom isgreater than CPU User Mode Utilizationon customer systems.•Hardware problems are the onlysituations on customer systems whereCPU System Mode Utilization exceedsCPU User Mode Utilization.March 2004 Copyright © 2004 HP corporate presentation.
