Yes, each SIP profile is in its own thread. That processes the SIP messages sent/received on the SIP profile. It's a relatively small part of the call - RTP is handled in a different thread. Some people have found on very busy servers that with a large volume of SIP messages to process the profile's thread became a bottleneck and adding a 2nd profile to handle some of the traffic helped. It might help increase the CPS your server can cope with, but probably won't make a difference to the maximum number of concurrent calls your server can handle. -Steve On 4 January 2011 16:30, Sam <u2nsam@gmail.com> wrote:
1 question from the link mentioned , there is a quote about "libsofia only handles 1 thread per profile"
the inbound calls will look into which profile so that we can increase threads by multiplying profiles ?

Well, the more processing power you have the more calls you can
We're in receipt of the details you recently sent us. Your order will now be processed as normal.
handle. You should make sure you're using 64bit.
There's a few tips on http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations too.

If you mute most of the callers, that would limit the audio that would need to be processed. -Avi

calls would not be TDM it would be ip-ip calls. Ok G711 uses less CPU than other codecs,how can i utilized multiple threading/profiles or any other options to scale ? as it would be an incoming call always on FS.

That will still involve transcoding. FS must combine all speaking channels into a single stream that can be sent to the conference members. That can't be done in a compressed audio format, so it must convert G711 to L16 for each speaking member, combine those pieces of audio, then convert L16 back to G711 to send to the conference members. Additionally, since the conference members are not necessarily all using the same codec that last transcoding step will occur once for each member, not just once for the conference. Your best bet is to use a codec that uses as little CPU for transcoding as possible - in software I'm not sure which is best there (G711 is simple so possibly a good choice), in hardware Sangoma D100/D500 would almost all the processing off the CPU.
