Apache AB 压力测试 

安装


// 安装工具 yum install httpd-tools


使用


// URL 是网站请求路径 ab -c 1000 -n 2000 "http://shop-app-envelope.mall.fenfenriji.com/envelope/data?enkey=d0hyf1or&uid=4040400&expires=1437460116&token=0f2aef4192f5374f85f844134ad14df5"

c并发量


n请求数

Document Length:        138 bytes  #HTTP响应数据的正文长度


Concurrency Level:      1000   #并发用户数  

Time taken for tests:   9.087 seconds  #所有这些请求被处理完成所花费的总时间  

Complete requests:      2000 #总请求数量，这是我们设置的参数之一  

Failed requests:        0  #失败的请求数量  

Write errors:           0  

Total transferred:      776000 bytes   #所有请求的响应数据长度总和  

HTML transferred:       276000 bytes   #所有请求的响应数据中正文数据的总和  

Requests per second:    220.10 [#/sec] (mean)     #吞吐率，计算公式：Complete requests / Time taken for tests  

Time per request:       4543.349 [ms] (mean)      #用户平均请求等待时间，计算公式：Time token for tests/（Complete requests/Concurrency Level）  

Time per request:       4.543 [ms] (mean, across all concurrent requests)  #服务器平均请求等待时间，计算公式：Time taken for tests/Complete requests，正好是吞吐率的倒数。也可以这么统计：Time per request/Concurrency Level  

Transfer rate:          83.40 [Kbytes/sec] received   #表示这些请求在单位时间内从服务器获取的数据长度，计算公式：Total trnasferred/ Time taken for tests，这个统计很好的说明服务器的处理能力达到极限时，其出口宽带的需求量。
