Thank you for your gracious response. To demonstrate just how long its been, I forgot to mention that I'm working with TSM 7.1.1, on some AIX (6.1 I believe) and RedHat on Intel (7.2?) servers.
I think I'll be running some basic network performance tests first. The throughput I'm seeing doesn't appear to match people's glowing descriptions of how big the pipes are.
