Most browsers are limited to 6 simultaneous TCP connections to a given domain when using http/1.1. See https://stackoverflow.com/questions/985431/max-parallel-http-connections-in-a-browser You might be able to increase this if you use a reverse proxy that supports http/2 such as NGINX. Note that MJPEG streams can be fairly network intensive so this may also present issues, especially over wifi.
