I am currently investigating performance and scalability issue on a
Murder. Right now, everything is working smoothly but I am trying to be
proactive as I expect a spike in usage in the coming week.
My question concern potential bottleneck in mail delivery. The way I
understand it, duplicatesuppression may constitute a bottleneck as
every incoming message have to be checked for in deliver.db and, if
delivered, written to it. I suppose only a single process at a time can
write to deliver.db, so does this constitute a bottleneck ?
Is there any gain in performance in setting duplicatesuppression to no ?
What are the implication of doing so, outside of performance ?
Thank you for your insight.
