And probably 10 to 20 additional configuration lines in your bacula-sd.conf For me it was like 30 minutes to read the vchanger documentation and to implement then just let it do its work. This in my opinion is much easier than creating a separate storage device for each pool or juggling storage devices to obtain concurrency.

It can also be the database or a number of other reasons. Also are you talking about Full backups? I ask that because usually Incrementals and Differentials spend more time looking for files then actually backing up data so these tend to have low rates however since they only backup a fraction of the Full backup they still finish much faster.
