We just upgraded our TSM server and a few clients with GigE adapters.
When I FTP a file from client to server, I am seeing approximately
65MB/sec.  When I backup the client I am only seeing 11 MB/sec.  Is
there a setting that I forgot to set/adjust?

The viability of that FTP test can be skewed by using a small file: try
to
either use a large file (GB or more) or a feeder mechanism as described
in
topic NETWORK PERFORMANCE, near the bottom of
http://people.bu.edu/rbs/ADSM.QuickFacts
which also describes other factors we have collectively found.
Ideally, the backup would use the same large file.
Network speed tests can become skewed if network buffers are quickly
absorbing
the modest data which is to be sent, whereas a much larger set of data
will
involve actual network data transfer and thus better average the
throughput
over time.  (Asynchronous buffering of I/O skews the view of reality.)
And there is always the TSM Tuning Guide.

That said, how does the 11 MB/s speed compare with the benchmark of your
previous network configuration, which is to say the same client and
server
arrangement, with only the pipe between them being different?
