Sounds like you're disk bound and the tape drive was never the bottleneck. Do you have any performance tools (PerfNav?) to verify when the save is running what the rest of the machine looks like? Silly question, but I've seen it before - you're using LTO3 tapes, right? Justin C.

Both were fiber attached from 5704 cards via IBM 2109-F16 SAN switch. Is there any option on SAVLIB that tells it to shift gears?
