High CPU load and "RTT aggregate"

Hallo folks,

currently I am running Jitsi on 18 cores (inlcuding hyper threading) of a Intel Xeon CPU E5-2680 v2 inside a KVM. The CPU load is about 40% for 50 clients. That looks quite high to me compared to the numbers given on the Jitsi website [1].

Also we are experiencing some lag sometimes. The “RTT aggregate” was about 1.5 seconds.

Is there anything I can do to improve the performance.

Thanks

Mebus

By profiling the JVB server we have noticed that it is configured to do some excessive logging, that takes the server down when load increase, you can disable the JVB server logging and improve performance by changing the following in /etc/jitsi/videobridge/logging.properties

much of the excessive logging on the JVB server started to appear when end users are overloaded so you may want to recuce the load on the clients as well by performing the following tweaks:
