We currently have a 720-9406 model iSeries AS/400 system. We recently upgraded are OS to version V5R3M0. We are using the system mainly for our payroll processing which occurs weekly, as well as we have the system set up as a web server which we have employees accessing throughout the day. Since the upgrade, our performance has taken a hit on the system, especially the web service piece of the system. Our ASP is currently at 68%. CPU varies as always, but at certain points in the day, especially when we process batch jobs for payroll, the CPU takes a signficant hit. We sometimes have to end the web server so that we can finish the processing. Does anybody have any suggestions on how to increase performance so that we don't have to end jobs or put jobs on hold.
Thanks for the help.
