I've lost track of whether you are using tape or not, so this post may
not be relevant.
Another issue to consider: is your tape drive being constantly fed with
enough data? Is is stopping and starting all the time? Start/stop can
affect throughput. However, the only two ways I know to avoid this is:
1 - steady stream of data from the FD to the SD
2 - data spooling, which means writing the data to local HDD then to the
tape.
I listen to my DLT drives. I can tell when they are streaming from one
end of the tape to the other from the sounds. I'm sure you can too.
Mind you, my drives are in a quiet basement...
