How did you measure? The througput value supplied by the fd is probably not measured the same way is it was with your old software. Spooling is nice if you do not want your tape go into start-stop-mode when doing incrementals. > What are the configuration items of bacula that influence its > throughput? > I guess it can have something to do with: > - signature = MD5 (In FileSet) > - compression (In FileSet; switched off) (Software) compression considerably slows things down. > - messages (but this overhead can't be that big, right?) > - MaximumNetworkBufferSize (set to 65536 in my sd and all fds, and > restarted of course) > > Unfortunately to no avail. > > Has anyone successfully managed to get over 10 MB/s? Again, I don't know how your measured. I can spool up to MIN(speed-of- spooling-device, network-speed) and then write to tape with up to approximately 45 MB/s. I configured bacula such that it can run three jobs at the same time, on three devices. What about your database speed? If you use MySQL turn on the slow query log to find problems with your db performance. Make sure you have all indexes set up properly -Sebastian _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
