Hi
i have been running scenario where several consumers connect to the same public queue (topic) the consumers connect via subscription manager. i have run several scenarios where multiple listeners use the same connection (different sessions) and scenario where listeners each have their own connection all of this has been run on TRUNC versions a while ago i started experiencing a serious down downgrade in performance when using such a scenario in the past the use of multiple listeners enabled me to enhance performance but currently it appears that i can achieve a faster performance while using 1 listener application in the past when several listeners used a shared queue - the message flow to between the consumers was not even (if using x listener one would expect to receive 1/x messages per listener) this problem/feature was corrected to support a pretty even distribution of the task as far as i can tell around the time this enhancement was made(it might not be connected but..) the performance started going down, and it is not a small difference using one listener i can achieve a speed of X for 100k messages per second using five listeners i experience a serious down grade of performance to ~5X for 100k messages per second this was not the case in the past and i am at a loss regarding this problem does anyone know , how this can be resolved Best Regards Mark
