I got 200 calls @ 7cps!!!!
Before you go into production with that figure in your head you should consider some
far more important questions.
How many file-descriptors are available to Asterisk? What was the maximum PDD? What was your load average in relation to the number of CPU cores after sustaining this for 5 minutes? Were any RTP packets arriving with a jitter of >50ms? How many rates were in the rate cards in total, how many call plans did they span, and how many call plans were exercised by the testing? Was each call to a different destination number?
I notice your total RAM usage is very close to 3GB, which is the maximum addressable by a 32-bit app. Are you sure you're running a 64-bit build of Asterisk so it can use >3GB RAM? On a related note, I notice the kernel is holding nearly 1GB of disk cache; perhaps you might consider allocating more RAM to the SQL server tuple cache.
Bear in mind that 7cps is an appreciable amount of traffic; given an ACD of 3 minutes this equates to 42 E1s (1,260 concurrent channels). You've already established that (given your current configuration) Asterisk is limiting to you 200 concurrent calls, so it's unlikely you'll have to deal with much more than 1cps on each machine.
