While I was developing an application with node.js I faced the need for the inter-process communication. Usually in such cases I use Redis Pub/Sub which provides, as a bonus, the possibility of scaling across several servers. But this time the question was specifically about the local exchange and its performance.

I decided to investigate existing options for the message exchange. This task is pretty standard and it is known as IPC (Inter-process communication). How can you implement IPC in NodeJS and how performant will the solution be? Let’s find out.
