概念：服务器并发处理能力的量化描述，单位是reqs/s，指的是某个并发用户数下单位时间内处理的请求数。某个并发用户数下单位时间内能处理的最大请求数，称之为最大吞吐率。 计算公式：总请求数 / 处理完成这些请求数所花费的时间，即 Request per second = Complete requests / Time taken for tests
并发连接数（The number of concurrent connections）
概念：某个时刻服务器所接受的请求数目，简单的讲，就是一个会话。
并发用户数（The number of concurrent users，Concurrency Level）
概念：要注意区分这个概念和并发连接数之间的区别，一个用户可能同时会产生多个会话，也即连接数。
用户平均请求等待时间（Time per request）
计算公式：处理完成所有请求数所花费的时间/ （总请求数 / 并发用户数），即 Time per request = Time taken for tests /（ Complete requests / Concurrency Level）
服务器平均请求等待时间（Time per request: across all concurrent requests）
计算公式：处理完成所有请求数所花费的时间 / 总请求数，即 Time taken for / testsComplete requests 可以看到，它是吞吐率的倒数。 同时，它也=用户平均请求等待时间/并发用户数，即 Time per request / Concurrency Level

我们只需要填写3个地方：1. host name 2.user name 3.password。hostname是虚拟机的IP地址。 最好是填写root用户时的用户名和密码。点击登陆就进入到Linux系统了 界面中，左边属于windows操作系统的目录，右边属于Linux（CentOS）操作系统的目录。可以用鼠标直接把文件拖过来拖过去的。
