real time chat
If people are communicating withing fluent community in the feed - what time delay is to be expected between responses? - i.e. time taken from writing a message to having it appear - under normal circumstances with a well functioning server
60 seconds has been my experience in side by side tests.
I believe its a JS based polling limit, attempting to prevent crushing servers with constant checks for no messages, as opposed to a server based delay.
Websocket connections would be best with near live feed, but currently using them within WordPress is not something feasible on most hosts.
