Hi Jim ,

One idea is to run a ftp from Domino Server to TSM Server and after that run 
the same with TSM. It is important clarify if your pb is reproduced with ftp. I 
should have 
taken into account the fs cache in your tests.

Asunto: Re: TDP for Mail (Domino) throughput

Jim -

You don't say what conclusions you drew from the included client
performance statistics.  If you haven't already, see the Performance
topic in chapter 1 of the TDP Domino manual for some perspective on
what your numbers indicate.  Whereas the Consumer session is
twiddling its thumbs waiting for buffer filling by the Producer
session, it suggests that the disk system that the database is on is
stinko, or that there are impediments to the I/O.  This is borne out
also in the ReadWrite vs. SendRecv numbers.  Ideally, you should have
benchmark data from when the disk system was introduced, to know what
it's throughput limits are, to compare against what you're seeing
now.  You can employ various monitoring tools in AIX to look for disk
contention, artificial degradation due to process re-nicing, etc.  I
should think that your Notes guy has already checked for a generous /
buffers value, but make sure.
