We have been working with a recent Jitsi Videobridge build where our Chrome clients report roughly a 2% level of packet loss when the system is under load. We have a build from October 2015 where the clients report only about 0.5% loss (at most) under that same load. We are looking for ideas as to where the packet loss might be coming from. The test infrastructure is the same, it is only the Jitsi version that differs.
Additionally, under even heavier load >80 users, the loss level rises to 5%, 25%, etc., while the older build still somehow keeps up.
