Hello, You can use tuning-primer and mysqltuner.pl to adjust some buffers. On my database, there is ONE message which will indicate what to do: [--] Reads / Writes: 1% / 99% That means that you have to focus on the write capability. To do it, I do it that way: - Use 5.1+ MySQL Version. - Use Barracuda InnoDB engine (that means using InnoDB plugin on 5.1 version, on 5.5, it's automatic) for all Bacula tables. - Size innodb_*_buffer_* to handle the night. I noticed that cleaning the database (using dbcheck) helps to control the database size and thus stabilize the performance. I do it on a weekly basis with a cron job: /usr/bin/yes yes | /usr/sbin/dbcheck -c /etc/bacula/bacula-dir.conf -C Catalog1 -b -f Hope this helps.
