I have jobs with unless 25 files and 200MB, running alone (no parallel
jobs in director and storage).
this should not a bottleneck to catalog !! :-(

I'm looking information in logs of executed jobs:
==============
Build OS: i486-pc-linux-gnu debian lenny/sid
JobId: 9727
Job: Respaldar_BDCatalogo.2009-03-12_00.10.17
Backup Level: Full
Client: "bacula-fd" 2.2.8 (26Jan08)
i486-pc-linux-gnu,debian,lenny/sid
FileSet: "MyCatalog" 2007-09-28 17:10:40
Pool: "Default" (From Job resource)
Storage: "Storage1" (From Job resource)
Scheduled time: 12-Mar-2009 00:10:00
Start time: 12-Mar-2009 00:56:59
End time: 12-Mar-2009 00:58:04
Elapsed time: 1 min 5 secs
Priority: 15
FD Files Written: 1
SD Files Written: 1
FD Bytes Written: 95,091,659 (95.09 MB)
SD Bytes Written: 95,091,772 (95.09 MB)
Rate: 1462.9 KB/s
Software Compression: 63.4 %
==============
this is a output of full catalog backup from director in one machine
and storage in other machine.
1 file - 1 jobs running - 100 MB - no more access/services in both
servers - and 1462 KBs of bandwidth.
:-(
thanks of any other idea.
