Hi, at the moment we are testing the Freewitch performance. The Freeswitch run on Windows Server 2012 R2 on a Hyper V The virtual maschine have an Intel Xeon 2,2 GHz CPU wiith 8 cores ( = max CPU performance 800%) Here some results: - 5000 SIP Registrations (reregister every 2 minutes) - 500 parallel calls (1000 channels) SRTP Opus without transcoding - Freeswitch CPU performance – 67% of possible 800% - That is a very good result! Now the transcoding part SRTP OPUS <-> RTP G711 - 500 SIP Registrations - 25 parallel calls (50 channels) SRTP OPUS <-> RTP G711 - Freeswitch CPU performance – 126% of possible 800% - 50 parallel calls (100 channels) SRTP OPUS <-> RTP G711 - Freeswitch CPU performance – 280% of possible 800% What is your experience? Are the transconding results ok, or to much?
