What is the file structure that you are backing up? Are there a LARGE amount
of small files the client needs to process? What is the copy serialization
set at for your copy groups. If you are backing up active files and the
copy serialization is set to make multiple attempts on an active file,
possibly that can add alot of time.
Just some wild guesses.

Subject: Re: Transfer Rate
The only client we have is where the server is located. We are running TSM
to backup one RS/6000 F50 server. And backing up 70 GB in 8 hours doesn't
seem right. Is there anything that I can do to speed this up. We run a
Magstar 3570 connected to the F50 server through SCSI.
TSM Version 4.1.2.0
AIX Version 4.3.3.0

Aggregate uses wall-clock time;
Network uses the intervals between when the client says "I'm sending data
now", to when the server actually receives it.
It's perfectly normal to have aggregate be a lot slower than network.
If you really want to speed up your backups, you need to
look at the accounting log records (.../server/bin/dsmaccnt.log - see admin
guide for layout)
to see which of your clients suffer most from idle wait, media wait, or comm
wait.
