We are having terrible performance with one of our instances of TSM.  I
have suspicions, but I want to hear what you guys say.  Here is what we
have:

2 instances of TSM - TSMI and TSMU (TSMI is the problem)

TSM 5.2.1.1
AIX 51.ML4
RS/6000 P670 - 8 processors, 16GB memory
Fastt700 SAN
STK9840 Tape drives

The Database is 85% of 88GB (with room to expand another 50GB or so).

Right at this moment, we have 233 sessions with TSMI.  The backup
sessions grind to a halt for hours at a time, with nothing apparently
happening.  I suspect that the directory trees are being downloaded and
built, but not sure

When we split TSMI and TSMU, we created the TSMU instance, and did a
full backup on all the servers that moved there.  The TSMI database is a
restored copy of the original database, with the TSMU stuff deleted out.

Any ideas would be greatly appreciated.
