This indicates aCPU bottleneck.•<strong>The</strong> 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 average<strong>and</strong> 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 <strong>HP</strong> corporate presentation.
