wrk 是用C語言寫的一套http benchmark 工具

可以幫助我們處理簡易的HTTP 性能測試

安裝 wrk

git clone https://github.com/wg/wrk.git
cd wrk
make

新版本wrk會自動幫我們檢查及安裝 openssl

如果執行過程發生 fatal error: openssl/ssl.h: No such file or directory

則手動安裝 openssl 即可：

sudo yum install  openssl-devel

測試

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

//or

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

命令列參數說明

-c, --connections: total number of HTTP connections to keep open with
                   each thread handling N = connections/threads
