I am planning to build an RN app using webRTC and I wonder first if someone has done some scalability testing. I wonder how many participants can be on the same conference, based on cellular connectivity or wifi connectivity ? And how this number looks like if we do audio only conferencing.
It will depend on a number of factors: resolution of the received video (in the video case), codec, number of cores of the device, etc. For the audio-only case, I don’t think you’ll have problems, but you could resort to mixing on the server side if you run into bandwidth problems.
