Three times our TSM Server has suffered from major performance problems.
All three times it turned out to be an undetected problem outside of our
TSM server.  One was a TCP/IP patch that was missed in an upgrade.  The
second time was with just one of our bigger clients with what seemed to be
the NIC settings, which in turn lead to the discovery of a faulty mother
board.  Once a new one was put in, the performance problem disappeared.
The last one was much harder to detect but turned out to be a problem with
a switch in a gateway ? (what the network guys told me : ) .  Our TSM
server is on our MVS OS/390 mainframe though so maybe the same things won't
apply for you.  I will tell you this though, each time the network guys
were positive it was within TSM and insisted that it could not be a
problem on their side.  They now think of TSM as one of their testing tools
whenever there are any changes implemented on their side as it seems to
detect problems no other tests do.
