Use all available CPUs with PM2

[El-Tommy]

I have a virtual machine with 4 CPUs, but as by default NodeJS only runs on 1 CPU, I wanted to take full advantage of this VM's potential to run my server with Socket.IO.

I saw this article in the Socket.IO documentation. If I use it, can I use all the CPUs and make the users, regardless of the room+CPU, able to communicate with each other?

Yes as document says

Please note that if you have several hosts each running a PM2 cluster, you will have to use another adapter, like the Redis adapter.

What if it is necessary to use it with HTTPs? How I do?

I noticed that when setting a port manually with httpsServer.listen(3001); the code doesn't work and the client keeps trying to reconnect.
