![]() Each spawned child has its own event loop, memory, and V8 instance. The Node.js Cluster module enables the creation of child processes (workers) that run simultaneously and share the same server port. We'll see how to create child processes with the Node.js cluster module and then later, we'll take a look at how to manage clustering with the PM2 Process Manager. Having multiple threads to handle requests improves the throughput (requests/second) of your server as several clients can be served concurrently. To take advantage of the other available cores, you can launch a cluster of Node.js processes and distribute the load between them. In this post, we'll take a look at an approach that can give you a quick win when it comes to improving the way your Node.js apps handle the workload.Īn instance of Node.js runs in a single thread which means that on a multi-core system (which most computers are these days), not all cores will be utilized by the app. ![]() ![]() When it is live, you'll want to use a Node.js APM. When building a production application, you are usually on the lookout for ways to optimize its performance while keeping any possible trade-offs in mind.
