That is "could" not "should" :)
Also consider compress "fast" if you are using "best".
Still get a lot of compression for much less cpu usage.

IIRC, there is a parameter to specify a start time for a DLE.
Perhaps you could stagger your clients so only a few are
dumping at the same time.
Make sure the spindle(s) for the holding disk do not contain
any DLEs that might be getting backed up at the same time.
The holding disk should be relatively unused. If you must
backup some part of the drive containing the holding disk,
then for those DLEs specify no holding disk and let them
go directly to {v}tape.
