I am getting anywhere from 4 to 40 M Bytes/second transfer rate.
sample from log (several lines omitted):

23-May 04:05 ip-bacula-sd JobId 3834: 3307 Issuing autochanger "unload slot 
10, drive 0" command.

>>From your replies it seems the issue is not the backup device but someone 
mentioned tools for the device and what you can use is itdt-dcr.  This program 
comes bundled in the downloads of firmware upgrades from Dell.  Go to 
support.dell.com and use the form to get to TL2000 updates or:

http://support.dell.com/support/downloads/download.aspx?c=us&cs=04&l=en&s=bsd&releaseid=R266766&SystemID=PWV_TL2000&servicetag=&os=LIN4&osl=en&deviceid=14489&devlib=0&typecnt=0&vercnt=10&catid=-1&impid=-1&formatcnt=0&libid=37&typeid=-1&dateid=-1&formatid=-1&source=-1&fileid=393643

There is also a WEB interface built in the TL2000 that can be turned on.

Also keep in mind that your Dell TL2000 may show up as IBM Model ULT3580-TD4, 
mine does because it was made by IBM for Dell.

My settings are like yours below except I don't have any of the lines below 
Autoselect.  I have Maximum Concurrent Jobs = 20 but each client is set to 1..

  All my servers have at least 2 ethernet ports and I use one on each server 
set to a static ip in the 192.168.0.x domain, all of which are connected to a 
gigabit switch not on the network and the backup server is also connected to 
this switch.  I only do one server backup at a time though.
