Cpu usage statistics are misleading before Oracle Solaris[TM] 10 Operating System

Applies to:Solaris Operating System - Version 8.0 to 9 9/05 U8 [Release 8.0 to 9.0]

For versions of Solaris[TM] prior to 10 the calculation of the cpu usage statistics as displayed in the user/system/idle columns of vmstat are calculated in a very simplistic manner.
This makes it possible for certain workloads to make vmstat produce highly inaccurate outputs for these columns.
