AFAIK, when bacula-sd run a copy job it perform this by single thread,
synchronous.
So, bacula-sd read a block from source volume, then write it into
destination volume, repeats until end of source volume.
This leads to about a half of expected throughput.

There was a thread on bacula-devel list about it: "slow copying from tape to
tape."
At this thread Kern confirmed a possible improvement:
