9Scaling Applications Using Multiple Processors in Node.js

In Chapter 4, “Using Events, Listeners, Timers, and Callbacks in Node.js,” you learned that Node.js applications run on a single thread rather than multiple threads. Using the single thread for application processing makes Node.js processes more efficient and faster. But most servers have multiple processors, and you can scale your Node.js applications by taking advantage of them. Node.js allows you to fork work from the main application to separate processes that can then be processed in parallel with each other and the main application.

To facilitate using multiple processes Node.js provides three specific modules. The process module provides access to the running processes. The ...
