Rsync Throughput issues

I am using Rsync between a Redhat Linux box and an AIX RS600. We have
a about 30gb of database we need to sync to a backup server. Sounds
good, right? The problem is that Rsync is so slow when we do the
initial dump. We have files that are 1 - 5gb. It takes around 14-20
hours to Rsync the file structure, which means our daily backup will
miss that days data because we are waiting for the data to rsync.
At first we were using ssh as the agent but we thought that might be
slowing us down. We then tried to use rsync as a server and push the
data to the module/zone of the server. Consistently, it takes roughly
2 minutes to transfer 10meg of data
I thought it was a network problem so we tried ftp. A 10 mb file took
90% the time (about 20 seconds. This is on a 100bit Full Duplex
switched network with both boxes on the SAME subnet.
Am I missing something? Should I expect these speeds? Could there be
something on the App switch throttling rsync for some reason?
Any thought will help,
