Tsm server 6.2.2 
OS redhat enterprise linux 6.0 
Client tdp for exchange, sqlserver, and backup archive client

Client connected via 1 gb ethernet connection.

In my experience, I yhave never been able to se throughput of much more than 
200 mb/s during a tsm backup, whether tdp or regular client.
I wonder, is TSM limiting a single session's bandwidth so as to insure 
availability for other client sessions which might begin; i.e. prevent one 
backup stream from monopolizing the server's network connection?

I have run ftp  and other tests to the server, and achieved throughput of 
around 800 mb/s over the same connection.
