Another BizTalk 2004 performance hint

Another BizTalk 2004 performance hint comes from TechEd 2004 as well: if you're sending multiple messages at once, wrap it in an atomic scope. This will create 1 persistence point instead of n (n being the number of messages you send). Persistence points are points at which BizTalk serializes the orchestration state into the MessageBox, draining the system from resources.
