I've seen where a very large bufpool setting can cause the TSM server to take 
longer to start but like Wanda said 20 minutes or so.  I've never seen anything 
longer than that.

Yes, thats about 600MB. Expiration doesnt run too badly. Expspeed says
we are doing about 2M pages per second. It seems like TSM grabs one
CPU, runs it at 100%, and very little I/O is occurring during all this
time. The DB is 90.3% of 35000MB, and the DB was reorged about 3 months
ago.
