Please, I am interested in the question.  
I have search for the requirements in RC documentation.  
I thought I can extrapolate the values there, the results are unrealistic.

Please to Rocket.Chat developers, help us.

Please for one rocket.chat message send, how many request is done to the database.

Maybe people that are running a RC server with a large amount of concurrent users can simply reply with their server specifications and experiences?
