Here is a great presentation I was just pointed to yesterday on
troubleshooting TSM bottlenecks from SHARE. It looks like it's a year old, but
it was new to me.
Most of the information I was aware of, but this is a good concise
presentation of how to do trace functions and interpret the output.

Subject: Poor Archive Performance
Hi folks,
Recently I've done several upgrades, and today I'm getting terrible archive
performance, although I don't do a lot of archives. My environment is:
TSM server on AIX
TSM server 5.1.6.4 32-bit, with 64-bit device support
AIX 5.1 ML04 64-bit kernel
TSM client on AIX
TSM client 5.1.5.15
AIX 4.3.3 ML 9 and ML 11 (two different clients with same problem)
Communications over SP Switch.
Here is an example, I finally killed the archive:

After 16 hours, barely anything had been done. I'm trying to archive /usr/ on
two aix servers (both 4.3.3).
I did some investigation, and I can't really see that anything is wrong. I did
notice that one CPU on my TSM server is pinned, which make me suspect that the
bottle neck is the TSM database.
I've looked through list, and have seen similar problems, but for a 4.1 and 4.2
server. Are they any problems with a 5.1 server?
Thanks Miles
