Maybe it's TIR issue. TIR always need to take time to collect the info for
backup.

If you have a slow slow system, maybe the speed for the
backup is dropping below the "magic" speed at which data
streams onto the tape. The effct is quite pronounced, esp.
for DLT. Listen to the drive - is it stopping and starting?

If so, increasing the multiplexing per drive might help. Try to
stream two or more clients onto the tape, subject to the usual
bottlenecks..
