Benchmarking Nginx with Go

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.

So, these are the different settings we are going to compare:

Go HTTP standalone (as the control group)
Nginx proxy to Go HTTP
Nginx fastcgi to Go TCP FastCGI
Nginx fastcgi to Go Unix Socket FastCGI

介绍

Spring从2.0开始引入了一个新的机制用于扩展xml模式，我们就可以编写自定义的xml bean解析器然后集成到Spring IoC容器中。

xml扩展大概有以下几个步骤：

编写自定义类
编写xml schema来描述自定义元素
编写NamespaceHandler新样式.css的实现类
编写BeanDefinitionParser实现类
把以上组建注册到Spring
