Unstable and Laggy Docker Deployment


Our Jitsi deployment through Docker is very unstable in the sense that it might become extremely slow and laggy. Where should I look for the problem? Is it because Docker deployment does not involve TURN server? It can be laggy even with 4-5 people. Here is the server spec:

CPU: 4 core
HDD : 40GB (Thin provisioning)

Watch server resources when this is happening, ram, cpu and bandwidth and see where is your problem …

Do we need to watch anything else?
Does JVB or any other component provide such statistics, for example, in log files?

Is there a tool that you recommend to use for monitoring it?
