Issues with Node.js Cluster Not Balancing Load Properly on Multiple Cores
I'm a bit lost with I'm a bit lost with I need some guidance on I'm working on a Node.js application that uses the built-in Cluster module to handle incoming HTTP requests more efficiently across multiple CPU cores... However, I've noticed that when I run my app, the requests aren't being distributed evenly among the workers. It seems like one worker is handling the majority of the load while others remain relatively idle, leading to performance bottlenecks. I'm using Node.js version 18.0.0 and the following basic setup: ```javascript const cluster = require('cluster'); const http = require('http'); const numCPUs = require('os').cpus().length; if (cluster.isMaster) { for (let i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('exit', (worker, code, signal) => { console.log(`Worker ${worker.process.pid} died`); }); } else { http.createServer((req, res) => { res.writeHead(200); res.end('Hello, World!'); }).listen(8000); } ``` I've verified that the load balancer is configured correctly and that the application is running in a production environment. Additionally, I tried using the `cluster.setupPrimary` method to configure the workers, but this didn't change the behavior. I also checked the environment variables to ensure that the app doesn't run in a single-threaded mode. When I monitor the CPU utilization, it shows that one worker is often maxed out while others are sitting at low usage. I'm wondering if there are any specific configurations or best practices I might be missing to ensure that the load is evenly distributed across the workers. Has anyone else encountered this issue? Any advice would be greatly appreciated! This issue appeared after updating to Javascript 3.11. What's the best practice here? I'm coming from a different tech stack and learning Javascript. What would be the recommended way to handle this? For reference, this is a production web app. I'm working in a CentOS environment. How would you solve this?
