[Freeswitch-users] Freeswitch performance issues

[Anthony Minessale]

Just a heads up.. Proxy Media Mode does not offer any support benefit and
may even be more intensive if not equally as intensive as not using it.
 Bypass media does require less resources because there is no media going
over the server and that puts a lesser load on the server doing I/O
operations.  To use either one as a variable you need to enable Late
Negotiation and set the variable before media establishment has taken place
on the inbound side of the call.

The leading cause of your performance issue will probably be the pretend
server its running on.
