node php 在性能上差不多。模拟实际应用进行测试对比了。有点小失望。

最近研究 node 主要 express+mongoose 对mongodb进行写入测试。

先会生成自增的_id 然后插入另外一个集合。PHP也是这么做的。用ab测试过。性能上node没比php好。

node开启了多线程，异步写入mongodb。mongoose 开启了16个连接池。居然都比php差一点点。

是我没搞好？有高手一起研究的没？

你这样测试,只能测试的mongodb 的性能吧…

而且node 那里来的多线程??是多进程吧…

实际项目，有大量的mongodb写入。这样的测试更接近实际项目。

你是怎么测试的?

node是按cpu数量开启多进程。

楼主测试的时候还是应该先找到整个系统的瓶颈，再去分析为什么用node没有性能上的提升…

这次node跟php都简单输出字符：fibo

结果还是一样。node没有比php好多少。甚至还差一点点。

node 代码如下：

var cluster = require(‘cluster’); var http = require(‘http’); var numCPUs = require(‘os’).cpus().length;

if (cluster.isMaster) { // Fork workers. for (var i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('online’, function(worker) { console.log(‘worker ' + worker.process.pid + ' start’); }); cluster.on('exit’, function(worker, code, signal) { console.log(‘worker ' + worker.process.pid + ' died’); }); } else { // Workers can share any TCP connection // In this case its a HTTP server http.createServer(function(req, res) { res.writeHead(200); res.end(“fibo”); }).listen(8000); }

php代码如下：

<?php

echo 'fibo’;

?>

你看下…??

这个是比较早的测试了,你按照他的方式在测试一次?

测试的源码在: https://code.google.com/p/node-js-vs-apache-php-benchmark/wiki/SourceCode

@youxiachai

测试了。结果一样。node比php 差。

看我日志： http://www.funfly.cn/archives/tech/nodejs/249.html

@dreawu

pi 计算那块做了没??

只是输出Hello world 部分,两者差距不大,我测试了好几次,拿最快的那次吧…其实这块两者差距不大…

@dreawu 你测试一下PI 计算部分…Node.js 明显比PHP 强太多了…

@dreawu 我只有apache的…你,试一下,把pi 计算也测来看看…

@youxiachai 看了你的博客,目测也是win 下的吧…求你的lamp 优化配置攻略.怎么测试,Node.js 都是好过PHP…

最终用两台同网段的centos机器测试。NODEJS.确实比PHP快至少两倍以上。

我的测试，是生成自增_id写MONGODB 使用 express mongoose
