In this session, we’ll focus on techniques to optimize the performance of Node.js applications, ensuring they run efficiently even under heavy load. Let’s begin by revisiting the fundamentals of Node.js and the event loop. Understanding Node.js Basi...
Welcome back! Before we delve into strategies for improving performance, it’s important to understand the potential pitfalls that can arise when the event loop is blocked in a Node.js server. To illustrate this, let’s build a simple example. Setting ...
Welcome back! In the previous discussion, we explored how blocking functions, such as a simulated delay, could severely slow down an entire server. Our delay function isn't a realistic scenario, so let's consider replacing it with a non-blocking call...
Optimizing Node.js Server Performance Introduction In this session, we explore a fundamental approach to enhancing the performance of Node.js servers. The key strategy is dividing a large problem into smaller, manageable pieces and distributing the w...
Welcome back! Our first approach to improving Node.js performance is by leveraging the built-in Node.js Cluster module. This module enables you to create copies of your Node.js process, allowing your server code to run side by side in parallel across...
Welcome back. Now that we understand the theory behind clustering, let's explore how to apply the Node.js cluster module to our servers and improve their performance. In this document, we'll modify our performance example code to create two worker pr...
