Node.js在Windows上表现不佳,当然它不能比基本I / O的apache慢

编辑：我的一个朋友刚刚在Linux上对相同的应用程序进行了基准测试,平均r / s约为7000.

编辑#2：我已经检查了Node.exe的cpu使用率,它只使用了5-6％的cpu.当一个四核机器上的这个数字应该是12％,如果在真正负载的情况下在单个线程上运行时,8个线程cpu应该是这个数字？

我编写了一个Node.js应用程序(运行Node v0.6.10)并使用apachebench进行基准测试：ab -c 256 -n 50000 http：// localhost：3000 /.我每秒钟收到大约650个请求的请求.这里有太多代码,但这是基本结构：

应用程序设置：

/**
 * Module dependencies.
 */
var util = require('util'),//Useful for inspecTing JSON objects
    express = require('express'),//Express framework,SIMILAR TO sinatra for ruby
    connect = require('connect'),//An integral part of the express framework
    app = module.exports = express.createServer(),//Create the server
    io = require('socket.io').listen(app),//Make Socket.io listen on the server
    parseCookie = require('connect').utils.parseCookie,//Parse cookies to retrieve session id
    MemoryStore = require('connect').session.MemoryStore,//Session memory store
    sessionStore = new MemoryStore(),Session = require('connect').middleware.session.Session,mongodb = require('mongodb'),//MongoDB Database
    BSON = mongodb.bSONPure,//Used to serialize JSON into BSON [binary]
    sanitize = require('validator').sanitize;

// Configuration
app.configure(function()
{
  app.set('views',__dirname + '/views');
  app.set('view ENGIne','jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());

  app.use(express.cookieParser());
  app.use(express.session({
    store: sessionStore,secret: '...',key: 'express.sid'}));
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

app.configure('development',function(){
  //app.use(express.errorHandler({dumpExceptions: true,showStack: truE}));
});

app.listen(3000);

console.log("Express server listening on port %d in %s mode",app.address().port,app.setTings.env);

io.configure('development',function()
{
  io.set('transports',['websocket']);
  //io.set('heartbeats',falsE);
  //io.set('heartbeat timeout',200);
  //io.set('heartbeat interval',220);
});

//MongoDB Database port and ip
var DATABASE_PORT = 27017;
var DATABASE_IP = "127.0.0.1"; //Localhost

/*
seTinterval(function(){
  console.log("BROWSING:\n" + util.inspect(browsing));
},1000);
*/

//Connected users
var validUsers = {};
var clients = {};
var browsing = {};

//Database handles
var users;
var projects;

//Connect to the database server
db = new mongodb.Db('nimble',new mongodb.Server(DATABASE_IP,DATABASE_PORT,{},{}));
db.open(function (error,client)
{
  if (error) {
    console.error("Database is currently not running");
    throw error;
  }  
  users = new mongodb.Collection(client,'users');        //Handle to users
  projects = new mongodb.Collection(client,'projects');  //Handle to projects
});

app.get('/',function(req,res)
{
  //users.insert("test",{safe:truE});
  //users.findOne("test",function(result){})    
  if(req.session.auth)
  {
    if(req.session.account == "client")
    {
      //Redirect to the client dash
      res.redirect('/dash');
    }
    else if (req.session.account == "developer")
    {
      res.redirect('/projects');
    }
  }
  else
  {
    res.redirect('/login');
  }       
});

除了上面的代码,唯一值得注意的剩余代码是一系列Express app.get和app.post事件处理程序.

我在基本的Express设置Web服务器和基本的node.js http Web服务器上执行了相同的测试.

Node.js与Express服务器

var express = require('express');
var app = express.createServer();

app.get('/',res){
    res.send();
});

app.listen(3000);

Node.js http

var http = require('http');
http.createServer(function (req,res) {
  res.writeHead(200,{'Content-Type': 'text/plain'});
  res.end();
}).listen(3000,"127.0.0.1");

结果是：
Express上每秒2000个请求
Node.js上每秒2200个请求

我对Apache Web服务器上托管的静态文件执行了相同的测试：
每秒6000个请求

现在这个基准测试@L_673_19@Node.js击败了Apache手！
