If you are using compression this is probably the main reason for
slowness. Tape drives can compress data at 80MB/s or more, I have
never seen a CPU that can do much more than 1/10 of that using gzip...

Turn off software compression. Put the database on a different
computer than the director.

Also do not expect high data rates for incrementals or differentials.
The client will spend a lot of time thrashing through the filesystem
to find the files to backup.
