[Red5] Minimize CPU usage

Check out earlier (few days back) messages in this thread. You can collect (view) everything you want with jconsole for realtime monitoring.

  Is there any way we can collect or log some kind of metadata for performance analysis?

  This could be setup optionally on any available deployment of Red5 and we could improve some items by analyzing such information.

  Just a rough Idea as I am not even aware if you guys does that already.

  Cheers,

  Ernani

    Hello Naicu,


    Yes, there is the audio and video streams...
    Streams from microphone and webcam. I organized
    bandwidth usage limitation for it too.


    Today we tested with 1500 concurrent connections
    and I got same result, 45%-50% usage of the 4 cores CPU.


    Unfortunately I can't show you because we use the cluster
    under internal LAN and there is no way to connect
    from internet because all 6 servers does not have
    internet connection.


    Anyway I'm working over JMX setup now hope will
    be able to give you guys more information.

      I think all connections are viewing a video stream in your case?!

      That's a pretty impressive setup! Can you give me the link offlist?

        Hello guys,

        I have 1 origin server and 5 nodes and about 1100 concurrent
        RTMP connections with live audio/video streams in different
        rooms.

        Origin server CPU usage is about 50%.

        Is it possible to minimize CPU usage with Java or
        RED5 tweaks?

        Thanks,
        Dan
