Apache ab 压力测试

简介

压测工具有很多，如：LoadRunner、JMeter、ab等等,LoadRunner和JMeter使用相对复杂，ab比较简单

Apache ab 下载与压力测试

下载

Apache VS16 binaries and modules download

 

 下载后解压

 然后用cmd进入apache24\bin目录，运行ab. (注意不能直接双击)

 然后运行压力测试， 比如

ab -n 5000 -c 100 localhost:8080/sync_result

5000个请求，每次并发100个请求。 localhost:8080/sync_result这个是URL， 默认超时时间是30s.

执行结果如下
