We are on W2K and have 57 threads with 259 interfaces. Our peak message flow is 198,000 per day. We have not seen any degradation in latency.
Our server has quad 1.5 gig processors and 4gb memory; development and production are separate servers. We’re going to add a second production server first quarter next year because we will be almost doubling our thread/message count, and didn’t want to take any chances.
