nodejs 集群未经过 siege 优化测试

问题描述

有人知道为什么我的集群没有优化吗？

文件：

const http = require('http');

require('dotenv').config();

const express = require('express');

const cassandra = require('./src/db/db');

const os = require('os');

const cluster = require('cluster');

const app = express();

const PORT = process.env.PORT;

const siege = require('node-siege');

if(cluster.isMaster) {
  const n_cpus = os.cpus().length;
  console.log(`FORKING ${n_cpus} cpus`);
  for(let i = 0; i < n_cpus; i++) {
    cluster.fork();
  }
} else {
const pid = process.pid;
const routes = require('./src/routes/index');

const cors = require('cors');

app.use(cors());

app.use(express.json());

app.use(routes);

const server = http.createServer(app);

  server.listen(PORT,() => {
    console.log(`Server listen on port ${PORT} `);
  });  

}

攻城命令：

siege -c100 -r1 http://localhost:3001/

Output:
