Do I assume you are using broadcast mode?
That would hint that the HTTP daemon core is very much not scalable, which
is quite possible.
With RTSP, there is one sending thread per elementary (RTP) stream, plus
one thread doing all the signaling. With HTTP there is one thread doing
everything for the whole system.
