[Freeswitch-users] Performance bottleneck

[Anthony Minessale]

9996 is not a good test extension because it does not generate any audio
unless it gets some.
9998 that generates a tone or make up an ext that plays a file is a better
one.

Processing of the sip calls can be delayed by the presence stuff which is
very intensive, you can try turning it off and see if you get more calls.
Also you should compare it to what happens with the test exten first in the
dial plan.
