title: COTURN using too much CPU !!. Is this normal?
body: <p>Thank you all,</p>
  <p>I have a video conference project developed using <strong>WebRTC API</strong> and I build my own TURN server using open source COTURN. According to my reads turn and stun servers are not cpu or memory intensive servers, but my turn server is using over <strong>90%</strong> cpu of <strong>8 core</strong> ubuntu server with only <strong>100 clients</strong>. Up to now I have managed to serve video conference service but now I am about to serve 75000 clients and I am afraid, with these numbers I am not able to manage it.</p>
  <p>Here is my TURN server configuration:</p>

  <p>Am I missing something?</p>
  <p>Is there any case that coturn(or any turn server) uses that much CPU?</p>
