Yes and no. I wasn't generally splitting streams across drives. I
could easily fit 6 clients on a single DLT IV media, not counting the
mail server but it had it's own class anyway, so I wasn't getting
multi-tape problems. I was seeing this transfer rate within a single
tape, no changing was ever done.
My copy was a one drive to one drive ration, one read and one write.
But as I said, no tape change ever took place on the clients I used to
test.
