node.js vs tornado

 

早就听说V8的威力了，由于一直在用tornado做项目，今天特意拿tornado和node.js来做个简单的对比压力测试。结果是node.js胜出。

 

硬件: 普通pc机 双核  内存2g

OS: ubuntu 10.04

 

先说一下node.js的安装：

wget -c http://nodejs.org/dist/node-v0.3.1.tar.gz

# ./configure

# make

# make install

 

如果需要ssl, 则先apt-get install libssl-dev

 

启动基于node.js的web server

脚本web.js如下:

 

var http = require('http');
http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello bobning\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');

 

# node web.js

Server running at http://127.0.0.1:8124/

 

启动基于tornado的web server

tornado就更简单了，在demos下有个helloworld项目，默认端口为8888

# ./helloworld.py --logging=error   #注意把log关闭，否则影响测试结果
