[Freeswitch-users] Freeswitch performance issues

Ok - my bad.

As described in
this<https://wiki.freeswitch.org/wiki/Proxy_Media#Common_misconceptions_.28READ_THIS.29>
FS
has 3 media handling modes.
In Proxy mode, FS just forward RTP from A-leg to B-leg with absolutely no
modification.

Question is how FS handle RTP traffic in Default mode if codecs on both
legs are same?
It is not just forwarding, right?
Which modifications/analysis undergoes RTP passing through the switch in
default mode?
I've take a look at sources and found dtmf detection, jitter, ptime, vad,
what else?
Which one most probable to cause poor performance?

Thank You.
