Hi all,

I'm relatively new to Bacula, but so far have been very impressed with
it. Right now, I'm backing up three separate data centers to Dell
2950s with 3TB SATA RAID 5 disk arrays. I'm running Bacula 2.2.8 on
OpenBSD 4.4 with Postgresql 8.3.3.

The only trouble I'm having is terrifically bad performance. As I
implied, this is backing up to an onboard disk array. My typical
backup is about 360MB, and the reported transfer rate is usually
around 1.5MB/s (despooling is around 30-40MB/s). This server is
connected to its clients via gigabit LAN, and these speeds are
suffered by all clients: good (dual quadcore Xeons with 16GB of RAM
and 15k SAS RAID 5 array) and bad (Soekris 5501 with solid-state CF
storage) alike; Windows 2003, FreeBSD 7, and OpenBSD 4.4; same or
different subnets.

Can anybody make suggestions for tracking down this performance
bottleneck? Below is a brief list of the steps I've taken, and the
results. Thanks for the help.

Steps:
---------
- Disabled spooling - transfer rate remained at 1-1.5MB/s
- Tested disk performance with dd - 100-200MB/s
- Disabled FileSet compression altogether - no change
- Enabled soft updates on /backups file system - no change
- Disabled GZIP compression - no change
