I was wondering if someone could clarify if I am understanding these rates correctly.

Aren’t the rates of messages sent per game server greater than the messages received for the entire game?
If I have 5 servers with 10 people, then each server can send 600 messages per minute (not counting initial which just makes it higher), but the amount of messages that could be received would be 250 per minute.
I’ll make a topic for creating lobbies. When the lobby is created it will send a message to the other lobby servers and update the lobby creation list. This will probably be done with a single topic. Does this mean that each lobby server will be limited to sending a message to update the player list 20 times per minute?
Why are the message/topic received rates so low when the rate at which messages can be sent are so high? Is there something I am not understanding correctly?
