NGINX tuning for best performance

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

express4.2源码解析

title: express4.2源码解析 date: 2014-05-18 15:00:50 categories: express tags: [nodejs, node, js, express]

express是nodejs平台上一个非常流行的框架,4.2.0是最新的版本,相比3.x版本优化了代码和api,去除了connect模块,自己实现了一个router组件,实现http请求的顺序流程处理,去除了很多绑定的中间件,使代码更清晰。

##1.使用express 如何使用express在官网有很好的讲解,只用experssjs实例app的几个函数,就可以构建构建web程序。

An example "always" behavior for ES6 promises. This only works if you do not create / return intermediate promises.
// A thing I want to do
// This flow only involves **one** promise, for example an ajax call
// None of the subsequent `then` or `catch` calls, return new promises.
var explode = false;
var promise = new Promise(function(resolve, reject) {
if (explode) {

1、简单的正则表达式:
(1)preg_match("/^(\d{18,18}|\d{15,15}|\d{17,17}x)$/",$id_card)
(2)preg_match("/^(\d{6})(18|19|20)?(\d{2})([01]\d)([0123]\d)(\d{3}) (\d|X)?$/",$id_card)
(3)preg_match("/(^\d{15}$/)|(\d{17}(?:\d|x|X)$/),$id_card)
