             Summary: codec opus performance issue
                 Key: ASTERISK-27747
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27747
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Codecs/codec_opus
    Affects Versions: 13.16.0
         Environment: AWS EC2 C4.2xLarge 8 core CPU and 8GB memory
            Reporter: Aaron An
            Severity: Critical


when transcoding from opus to others (for example g711), asterisk have a 800% cpu used when concurrent calls is only 60-70. All 8 core cpu were used, this make the choppy sound.

my codec.conf:
[myopus]
type=opus
packet_loss=5
complexity=6
max_bandwidth=narrow
signal=voice
application=voip
max_playback_rate=8000
bitrate=12000
cbr=1
fec=1
dtx=0

and then i change the option complexity to 0(lowest cpu), when 60-70 concurrent calls, cpu used decrease to around 300%. is there any suggestions to increase the calls? I have read the article about opus before, it say that opus load is 3X to g729,is that true? how to improve?
