You might want to take some advise on how to tune your database and the hardware (raid controler with writeback for example) that is related. Your shared_buffer and your wall_buffers are probably too small, and running with fsync=off is just not something you can use in production. Please, also have a look to your database and see if your server is properly sized, a good indicator is that the Filename table should more or less fit in memory to have good performances with large jobs. Using a recent version of Bacula (probably 5.2) should also help a bit using the batch session limit feature.
