[Box Backup] local backups really slow

[boxbackup@fluffy.co.uk]

Hi,

I'm trying to backup to a server running on the local machine to set up a disk
I'm going to use at a remote site. I figured a local backup would be much
faster than having to back up 40G of data over the net. However, it's not
nearly as fast as I expected. It seems to only be going at about 200K/s, which
is paltry in comparison to the M/s rates I see when doing local rsyncs. The
src and destination drives are on different IDE busses.

Does that seem really slow to those of you using box backup, maybe over a
local lan? Might have have some real simple setting wrong? It's not a slow
machine - Athalon 2G, with 2.5G of memory.. CPU usage (per top) is running
about 10% user and 88% wait, and has been for several hours. The client/server
addresses are on the loopback interface.

Any ideas on why it's so slow, or how I could speed it up?
