Assuming you're running a fairly recent Linux distro, and assuming your active
network interface is eth0, run:
ethtool eth0 | grep Speed
and make sure you actually have a network connection that can push more than
100Mbit/sec!

[Bacula-users] Bacula transfer limited 100Mbit/s
When spooling to disk I still get only a max of 100Mbit. When writing to tape
I get exactly the same network transfer speed. Here is a screen shot of a run
with spooling enabled.

Those dips are when the 20GB spool is written to the tape. Notice that the
dips are much shorter which means the Tape drive is faster than the network
speed.
I have an TL2000 w/dual LTO5 and when running the btape speed tests I get the
the following results:
zero data = 146.4 MB/s to 189.4 MB/s
random data = 56.51 MB/s to 116 MB/S
zero data and bacula block structure = 111 MB/s to 151.5 MB/S
The slowest tape speed (56.51 MB/s = 452 Mbit/s) is still way faster than the
network transfer speed.
Though now that i'm running a test rsync I'm getting the same bandwidth
limiting.. odd, so it's probably not bacula at all.
