If the node js server is single-threaded and occupies 1 processor core, then it will be rational for the game server to run several servers?

Question

Node.js

Hello, I am writing a game where, for example, two players connect to a web socket room for two connections and a game simulation is created for this room to synchronize actions.
For example, I have a server on port 8001, in which, let's say, there will be about 50 rooms maximum.
Essence of the question: if we proceed from the fact that node js is single-threaded and uses one server core, will it be rational to run as many servers and on different ports as there are processor cores?

Answer 1

Yes. And write a room broker so that he knows where which room is.
