Linux上编译安装:
[root@centos ~]# cd /usr/local/src [root@centos ~]# yum install git -y [root@centos ~]# git clone https://github.com/wg/wrk.git [root@centos ~]# cd wrk [root@centos ~]# make [root@centos ~]# ln -s /usr/local/src/wrk/wrk /usr/local/bin
参数说明: -t 需要模拟的线程数 -c 需要模拟的连接数 -d 测试的持续时间 –timeout 超时的时间 –latency 显示延迟统计
wrk -t12 -c400 -d30s --latency http://www.baidu.com 输出: Running 30s test @ http://www.baidu.com 12 threads and 400 connections Thread Stats Avg Stdev Max +/- Stdev Latency 933.14ms 415.00ms 2.00s 77.56% Req/Sec 24.77 15.65 121.00 70.04% Latency Distribution 50% 711.85ms 75% 1.24s 90% 1.56s 99% 1.90s 8181 requests in 30.10s, 121.83MB read Socket errors: connect 0, read 0, write 0, timeout 1545 Requests/sec: 271.82 Transfer/sec: 4.05MB
以上使用12个线程400个连接,对baidu首页进行了30秒的压测,并要求在压测结果中输出响应延迟信息。以下对压测结果进行简单注释:
Running 30s test @ http://www.baidu.com(压测时间30s) 12 threads and 400 connections(共12个测试线程,400个连接) Thread Stats Avg Stdev Max +/- Stdev (平均值) (标准差)(最大值)(正负一个标准差所占比例) Latency 933.14ms 415.00ms 2.00s 77.56% (延迟) Req/Sec 24.77 15.65 121.00 70.04% (处理中的请求数) Latency Distribution (延迟分布) 50% 711.85ms 75% 1.24s 90% 1.56s 99% 1.90s (99分位的延迟) 8181 requests in 30.10s, 121.83MB read(30.10秒内共处理完成了8181个请求,读取了121.83MB数据) Socket errors: connect 0, read 0, write 0, timeout 1545 Requests/sec: 271.82 (平均每秒处理完成271.82个请求) Transfer/sec: 4.05MB (平均每秒读取数据4.05MB)
