在Ubuntu上优化Node.js性能可以通过多种方式进行,以下是一些建议:
sudo apt update curl -sL https://deb.nodesource.com/setup_22.x | sudo -E bash - sudo apt install nodejs cluster模块来充分利用多核CPU,提高应用的可伸缩性和性能。const cluster = require('cluster'); const http = require('http'); const numCPUs = require('os').cpus().length; if (cluster.isMaster) { console.log(`Master ${process.pid} is running`); // Fork workers. for (let i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('exit', (worker, code, signal) => { console.log(`worker ${worker.process.pid} died`); }); } else { // Workers can share any TCP connection // In this case it is an HTTP server http.createServer((req, res) => { res.writeHead(200); res.end('hello world\n'); }).listen(8000); console.log(`Worker ${process.pid} started`); } 通过上述方法,你可以在Ubuntu上优化Node.js的性能,确保你的应用能够高效运行。
