背景
最近用 Go 重写了之前用 PHP(Laravel) 写的一个较复杂的接口， 顺便作了个简单的性能测试对比。
目前网上很多性能对比只是简单的作一个 hello world 的对比， 基于实际业务的对比较少，所以记录一下这次对比结果。
HUGOMORE42
业务场景
这是多一个类似于获取商品详情的接口， 面向的用户是商店工作人员。多商家，每个商家可自定义自己的商品字段。
服务端收到请求大约做了这几件工作：

== 请求 ==
User -> WebService: 请求
note right: 请求中带 JWT 信息 JWT 中只包含用户 uuid、商家名称）
== 用户身份 ==
WebService -> MySQL:查询用户信息
MySQL --> WebService: 返回数据
WebService -> MySQL: 查询商家信息
note left: 商家基本信息、配额信息、商品自定义字段信息
MySQL --> WebService: 返回数据
== 商品信息 ==
WebService -> MySQL: 查询商品数据
MySQL --> WebService: 返回数据
... 组装商品数据 ...
== 输出 ==
WebService --> User: 输出JSON

先表明一下观点， 在一个项目运作过程中（特别是在初期）性能并不是首先要考虑的因素 ，所有读取数据操作均 未使用缓存 （初步估算用户增长规模 项目上线第一年基本不会出现性能瓶颈， 在最经济的人力、物力资源下快速推出新功能才是最重要的 😏 ）。
测试环境
硬件： 阿里云 ECS 2核 4G内存 （购于2014年2月，普通云盘）
操作系统： CentOS 7.3 64位
测试工具： apache ab
为减小因带宽因素影响，测试使用内网网络(Go直接使用内网IP、PHP更改 hosts 文件， 请求从局域网内另一台 ECS 服务器发起)；
机器上同时运行有其它服务。

测试数据
PHP: .php -c 600 -t 10
先直接直接输出 helloworld.php 以反映机器大致性能情况。
