To reiterate what others have stated: 1) What hardware (zSeries Server) are you running on? 2) How do measure the increase? 3) What tools are you using to measure your usage? 4) Were any applications recompiled for the upgrade? 5) Any other changes done at the time of the upgrade? Network changes, Firewall changes, Software changes other than z/OS, etc. ? 6) Where are you seeing the increase? Define CPU USAGE
