I am working on a very extensive load-testing for capacity planning project analyzing Jitsi and various related components in educational and other settings, for my current employer. In the current load-testing I have hit a hard limit around 600-650 users for a default-install standalone all-in-one Jitsi server. This is not expected behavior. I am hoping the JItsi community can help determine if it is as simple as a configuration tweak, or if it is a more serious bug.
