I think you should use /dev/random, not /dev/zero unless hardware
compression is disabled in order to have more realistic figures.

Re: [Bacula-users] LTO3 performance
The output test was:
dd if=/dev/zero of=/dev/nst0 bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB) copied, 7.80926 seconds, 134 MB/s
I have a server let say A that has director and storage daemon with a
DAT72 and other server say B which has storage daemon and a LTO3
drive.
A and B has on the same Gigabit network and backup server on that network.
Thanks you I added spooling, but I haven't collected relevant data to
say it is an improvement, if you want I can send part of my
configuration...
thanks everyone
