命令:

ab -n 800 -c 800  http://192.168.0.10/ 

说明:
(-n发出800个请求,-c模拟800并发,相当800人同时访问,后面是测试url)

命令:

ab -t 60 -c 100 http://192.168.0.10/ 

说明:
在60秒内发请求,一次100个请求。

命令:

ab -t 60 -c 100 -T "text/plain" -p p.txt http://192.168.0.10/hello.html 

说明:
如果需要在url中带参数
p.txt 是和ab.exe在一个目录 
p.txt 中可以写参数,如 p=wdp&fq=78
