Hello everyone! I ran mediasoup on server. When limit is reached 320 users, 20 broadcasters(with camera and microphne) and 300 watchers(without camera and micro). At this moment I checked resources on server by htop and see that memory usage was 12Gb. What’s the reason of consume memory? I understand that why mediasoup uses cpu, but I’ve not found anywhere information about memory usage. Thanks for response!
