node.js vs tornado

bobning

 
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
