[Freeswitch-users] How to calculate server requirements for Freeswitch.

It was a load test with sipp... The scenario was sipp generated calls into
freeswitch with its media reflector turned off, freeswitch answered the
calls and played back a static audio file... Call duration was 30 seconds at
which time the calls were hung up, sipp was set to originate 1000

Now, that being said only a moron would put 30K concurrent calls on a single
x86(_64) server imho... If that server were to be down its costing
$18,000/hour (assuming revenue of $0.01/minute). And you know Murphy¹s Law
dictates you would probably be down a few hours a month... Its just smarter
(and probably cheaper) to deploy 15 to 20 boxes and have a single node
failure not affect over all max call handling capacity
