Turn on the auto tuner. System value QPFRADJ. Of course, this all depends. On the size of your system. On the number of jobs. On the number of users. On the diversity of the applications running. On and on and on... System tuning info, best place? (IMHO) COMMON. Barring attendance there, the best place to start is the AS/400 Performance Tools book. If you don't have the performance tools installed (quick way to check, see if the WRKSYSACT command exists, if it does, you have the tools) then see the above two items of advice. Can it be done in a day? Maybe if the performance issue is HUGE and the cause is HUGE and glaring. Can it be done in a week? Maybe if the performance issue is HUGE and the cause is Medium and glaring. Probably take much longer to do any REAL tuning. Need to monitor system over time and evaluate that. Need to understand application mix and usage over time and evaluate that. Need to understand hardware and limitations. Need to understand user expectations and manage them. Need to understand management expectations and either manage that or get them to ante-up. =========================================================== R.
