We currently have around five concurrent APNS connections open at a time. We want to maintain as any open connections as we reasonably can without the connection being refused. Nothing crazy, but we do want to make sure our connections won't be closed if we start to have around 20-30 open.
This Stack Overflow question seems to settle on around 15 connections being the max (because of this conversation from 2010). Is there any more concrete information regarding this?
