I believe the whole dump has to be done before it starts to write to tape. This prevents incomplete dumps from wasting space on the tape.
I try to have numerous smaller DLEs, so that it takes several DLEs to fill a tape. Thus, when any one of them is finished, it can start going to tape. If you have only a single DLE which occupies the whole tape, then it does seem slower. In that case, perhaps you don't even bother with a holding disk?
