We split into 3 sites when we were nearing 40 threads in one site. We have 3 sites, 12 processes and 49 threads. Our peak message throughput is around 160,000 per day. Our CPU usage rarely goes over 20%.
We were told by McKesson that W2K is only ‘certified’ for a peak throughput of 250,000 messages, after that Unix must be used. We will be very close to 250,000 toward the end of next year; because of this, we will be adding an additional production W2K server early next year.
We were also told that once you upgrade to the 5.x platform that on W2K you must have 1GB memory per processor, so we will need to upgrade our production server before we can do that.
