The key is "will be". So be patient.
Alternative is list archives - performance considerations were many times
discussed.
Third option might be DB2 docs. Basic DB2 performance tuning looks just
like TSM DB tuning but is having more switches and levers ,-) On the end
internal TSM DB is just the DB2 code at version 1 or 2 with some
functionality stripped out. Single DB instance, unknown number of
tablespaces (with no individual control), single bufferpool for tables and
indexes, etc.
The only curious thing (for me) is that DB2 does have a tablespace limit
of 64 GB if 4kB pagesize is used. And even if TSM uses separate
tablespaces for BACKUPS, CONTENTS and AS.Segments tables it is unknown
what can happen if any table reaches this limit (and is this a limit for
TSM). On the list I've seen client, driver, TDP developers, support people
but not yet server developer (or I missed him/her) to reveal the mistery
:)
So if you need a book right now just ask a DB2 admin for some hints or
visit DB2 docs site and read few chapters there.

Subject:        TSM 5.1 Performance Tuning Guide - Where?

The README.SRV file for AIX Server 5.1.1.1 update says that, "The IBM
Tivoli Storage Manager V5.1 Performance Tuning Guide will be available
on the home page. Point your web browser to this address:
          http://www.tivoli.com/support/storage_mgr/tivolimain.html "

I can't find it.
