Your posting contains no information on what analysis you've done to
gain perspective on the problem, and the dominant area in which time
is being consumed.  Valuable basic information can be had by
performing repeated Query SEssion commands as the backup session
starts, and as it runs.  You can see if the active-files inventory
transfer during start-up is taking a lot of time by seeing the TSM
server outbound traffic continuing to climb over time, with
essentially no inbound.  After a backup, Query Node Format=Detailed
will provide numbers on wait times.  The TSM accounting records will
have further such data.  If necessary, you can run a client trace as
outlined in the Problem Determination Guide to get a good picture of
resource consumption.  Knowing where the problem area is, is vital to
its treatment.
