Question

我实现了即时消息Web应用程序。我想在我的mongodb数据库中保存聊天消息。如果每秒200条消息被推送到我的服务器花了30％我的CPU核心。我认为我的node.js Web应用程序性能不佳。你能帮助我为我的即时消息Web应用程序实现一个好的架构吗？我想从客户端到服务器每秒至少推送5000条消息，这些消息在我的CPU核心上花费不到50％。

由于

这是我的app.js

// Setup basic express server
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io')(server);
var port = process.env.PORT || 3000;
var mongoose = require('mongoose');
var configDB = require('./config/database.js');

// Database Models ===============================================================
var Message = require('./models/message');

// configuration ===============================================================
mongoose.connect(configDB.url);

server.listen(port, function () {
  console.log('Server listening at port %d', port);
});

io.on('connection', function (socket) {

  // when the client emits 'new message', this listens and executes
  socket.on('new message', function (data) {
    // we tell the client to execute 'new message' 

    var message = new Message({text: data});
    message.save(function (err) {
        if (err) return handleError(err);
        console.log('saved ' + data); 
    });

    socket.broadcast.emit('new message', {
      username: socket.username,
      message: data
    });
  });

  // when the user disconnects.. perform this
  socket.on('disconnect', function () {
  });
});

配置/ database.js

module.exports = {

    'url' : 'mongodb://localhost/chatdb'

};

message.js

var mongoose = require('mongoose');  
var messageSchema = new mongoose.Schema({ 
    room_id: { type: String, required: false },
    member_id: { type: String, required: false },
    text: { type: String, required: false },
});

var Message = mongoose.model('Message', messageSchema);

module.exports = Message;
