Enhanced Use Case for single-node Node.js to Cluster Module
Improving single-node performance in Node.js is a common challenge developers face, as Node.js’s single-threaded nature can limit its ability to handle high concurrency or heavy load in some applications. To enhance performance, you can consider a variety of solutions and techniques. Below are some common methods:
Using Multi-process or Multi-threading Techniques
(1) Node.js Cluster Module: The cluster module in Node.js allows for multi-process applications, enabling each CPU core to run a separate Node.js process. This can significantly improve the application’s concurrency performance.
(2) Worker Threads: The built-in Worker Threads in Node.js help you take advantage of multi-core CPUs for parallel computation. You can use Worker Threads to handle long-running computational tasks without blocking the main thread, thereby enhancing concurrency handling.
(3) PM2 for Monitoring and Multi-process Management: Using PM2 to configure multi-process mode for starting and managing Node.js processes can improve the application’s stability and resilience. PM2 automatically handles process restarts, load balancing, and other settings, making it easier to manage Node.js applications in production.
In this article, we will focus on introducing the Cluster module.
