server.js

const http = require('http');

const hostname = '0.0.0.0';
const port = 1337;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.end('Hello World!');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

});

swoole.php

<?php

server.go

package main

import (
    "fmt"
    "log"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello World")
}

func main() {
    http.HandleFunc("/", handler)
    log.Fatal(http.ListenAndServe(":8080", nil))
}

测试命令为：ab -c1000 -n30000 http://127.0.0.1:1337/
