CPU usage jumps to 50% for just three users

Description

I have deployed the Jitsi video bridge according to the install docs on jitsi meet.

Current behavior

The CPU usage is low (<1%) when there are no meetings as expected. However, when just 3 people join a single meeting, the CPU usage immediately jumps to 50%. This seems abnormally high if you think about that only a few more people would fill the maximum capacity of 400% CPU usage (with 4 cores). The CPU increases when more meetings are created or more people join the call.

Expected Behavior

A lower CPU usage.

Possible Solution

Steps to reproduce

  1. Install the Videobridge. I used a Hetzner 15€/month machine (CPX31) at https://www.hetzner.de/cloud.
  2. Run a meeting with 3 people/devices.

Jitsi Meet videobridge: 2.1-183-gdbddd169-1 Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0-91-generic x86_64) A Hetzner 15€/month machine (CPX31) https://www.hetzner.de/cloud
