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.
