Do you have general benchmarks for maximum connections on your server?
Tests were run against an AWS m5.large instance (2 CPUs with 8GB memory, 2GB allocated to java_heap).
Publishing a 240p (426x240, 200 kbps) stream via RTMP, we were able to achieve the following while still maintaining quality of stream:
WebRTC = 500 Subscribers
RTSP (Mobile) = 2,000 Subscribers
RTMP = 1,200 Subscribers
The same server type can support approximately 60-70, 480p RTMP publishers or 30-40 480p RTC publishers.
