wrk-伺服器壓力測試工具的使用(一)

github位址:https://github.com/wg/wrk

一、安裝

Ubuntu/Debian

$ sudo apt-get update
$ sudo apt-get install build-essential libssl-dev git -y
$ git clone https://github.com/wg/wrk.git wrk
$ cd wrk
$ sudo make

//move the executable to somewhere in your PATH, ex:
$ sudo cp wrk /usr/local/bin
           

CentOS / RedHat / Fedora

$ sudo yum groupinstall'Development Tools'
$ sudo yum install openssl-devel
$ sudo yum install gitgit clone https://github.com/wg/wrk.git wrk
$ cd wrk
$ make

//move the executable to somewhere in your PATH
$ sudo cp wrk /somewhere/in/your/PATH
           

其他系統參考:https://github.com/wg/wrk/wiki

二、使用

wrk的使用非常簡單

一行指令搞定

$ wrk -t12 -c400 -d30s http://127.0.0.1:8080/index.html
           

// 運作30s,開啟12線程,總共保持400個HTTP連接配接開啟

三、wrk報告

Running 30s test @ http://127.0.0.1:8080/index.html

12 threads and 400 connections

Thread Stats  Avg      Stdev    Max  +/- Stdev

Latency  635.91us    0.89ms  12.92ms  93.69% 

Req/Sec    56.20k    8.07k  62.00k    86.54%

22464657 requests in 30.00s, 17.76GB read

Requests/sec: 748868.53

Transfer/sec:    606.33MB
           

結果也不難了解。

latency那一行反映了請求響應時間,分别為平均值,标準差,最大值,正負一個标準差内的比例;

transfer為資料交換量。

其他都很好了解,無須解釋了。
