To support mysql, they break performance for _every other_ database system? <cynism> Now, I understand how the mysql people manage to spread the legend of mysql being fast.

Well, if you read the documentation, you will see that it will only wait if there are at least commit_siblings other transactions active. So when Bacula serializes access, there will be no delays, as there is only a single transaction alive. HTH Markus -- Markus Schaber | Logical Tracking&Tracing International AG Dipl.
