Do you see spooling taking place? If so, it is probably just not enough
as the other individual said.
As for no speed increase, keep in mind, the backup will actually take
LONGER as part time it's reading from disk and part time it's writing to
tape, but there will be load on the -fd for a shorter period of time.
