The network transfer rate is not particularly useful (see APAR IC30767),
so don't use that to judge your TSM performance. If you want a reasonable
idea of what how fast your TSM client can push data, your best bet is to
do a selective backup of a very large file (say, several hundred or more
MB), and look at the aggregate data transfer rate.

The only dumb question is the one that goes unasked.
The command line is your friend.

Try running FTP.  Send a sizeable file (at least 100 MB) from your client
machine to the TSM server, several times, and see if you can get a
consistent MB/sec throughput rate.

If it is about the same as your TSM backup throughput, then the problem is
network related.
If it is a lot faster, then look for something in TSM, or in the client
file
system.
