在Ubuntu上提升Node.js运行速度可以通过以下几种方法实现:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
source ~/.bashrc
nvm install node # 安装最新版本的Node.js
nvm use node # 使用安装的最新版本
npm config set registry https://registry.npm.taobao.org
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`);
}
node --prof
生成CPU分析器报告,分析瓶颈并进行优化。fast-json-stringify
替代JSON.stringify
。通过上述方法,你可以在Ubuntu上提升Node.js的运行速度和整体性能。
