[Freeswitch-users] Transcoding Performance OPUS <-> G722

[Alexander Haugg]

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?
