PM2 uses the node cluster module to run the application cluster mode.
The cluster module supports two methods of distributing incoming connections.
The first one (and the default one on all platforms except Windows) is the round-robin approach, where the primary process listens on a port, accepts new connections, and distributes them across the workers in a round-robin fashion, with some built-in smarts to avoid overloading a worker process.
The second approach is where the primary process creates the listen socket and sends it to interested workers. The workers then accept incoming connections directly.
So my question is, Which approach is used by PM2 to run the application in cluster mode?
If you know the answer let me know.
