Distributed instalation with sound quality problems when a lot of users

Hi!, thank you for your amazing project, it’s really awesome what it can do!.

Now I’m trying to improve an existing installation of jitsi-meet,

Original it was a all-in-one installation, Prososy, Jicofo, Video-Bridge and JIBRI in one big server on AWS.

Now I extracted VideoBridge and JIBRI to other instances, now the infra is like this:

4 x c5.4xlarge for Video bridge instances


Resource consumption:
Total conferences

Total Participants

*Conferences per VideoBridge: *

*Participants per VideoBridge: *

CPU per Video bridge


When there is more than 30 users per conference, lot of them experiments degradation on audio (normaly no use of video)

I made some tunnings like limit number os video senders, disable stadistics, limit to 480 the resolution, set the memory os java process to 16gb (VIDEOBRIDGE_MAX_MEMORY=16192m
), tunnings to the Linux and ethernet, etc. but still experiments problems when more then 30 users per conference.


Maybe I’m forgetting something, or there is another way to distribute load between VideoBridge instances, maybe reduce the amount of cpu and memory per instance and duplicate the number of VMs… please… any idea?

Thank you again!!!

have you considered that the limitations could be on the clients rather than the server ? Browsers are not real time operating systems. There are threads on disabling UI elements to optimize for high number of participants but I’m too lazy to search the forum for you.

hahahahahahaha nice try!
