Assuming all things equal in an ideal world, the cpu usage by this app would be constant, the R/T would be constant, the I/O overhead would be constant. Given that performance is erratic, but cpu usage is consistently less than 5%, then it would seem it's more a question of I/O waits, not I/O processing. I would look at resource contention, e.g. channel, device, etc. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
