我们先对ApacheBench做个简介，再介绍boom。 ApacheBenchApacheBench简介ApacheBench 是一个用来衡量http服务器性能的单线程命令行工具。原本针对Apache http服务器，但是也适用于其他http服务器。 ab工具与标准 Apache源码一起发布，免费，开源，基于Apache License。 ApacheBench安装ubuntu 14.04 执行“apt-get install apache2-utils“即可。 ApacheBench快速入门发送1000个http get请求到http://192.168.10.232:8000/blog，并发为10:

boomboom简介boom是python替代ab的模块，并增加了部分功能。 boom安装ubuntu 14.04 执行“pip install boom“即可，注意可能需要先执行"apt-get install libevent python-dev"。它使用Gevent创建虚拟用户，使用Requests发送请求。 boom快速入门# boom -n1000 -c10 http://192.168.10.232:8000/blogServer Software: tracd/1.0.1 Python/2.7.3Running GET http://192.168.10.232:8000/blog Running 1000 times per 10 workers.[================================================================>.] 99% Done-------- Results --------Successful calls 1000Total time 1355.1412 s Average 13.5156 s Fastest 8.2434 s Slowest 15.3094 s Amplitude 7.0660 s RPS 0BSI Hahahaha-------- Status codes --------Code 200 1000 times.-------- Legend --------RPS: Request Per Second BSI: Boom Speed IndexAverage：每批请求的平均处理时间。 Fastest：每批请求的最快处理时间。 Slowest：每批请求的最慢处理时间。 Amplitude：振幅，即最慢与最忙批次处理时间差。 boom参考

--version Displays version and exits.
-m {GET,POST,DELETE,PUT,HEAD,OPTIONS}, --method {GET,POST,DELETE,PUT,HEAD,OPTIONS}
HTTP Method --content-type CONTENT_TYPE
Content-Type -D DATA, --data DATA Data. Prefixed by "py:" to point a python callable.
-c CONCURRENCY, --concurrency CONCURRENCY
Concurrency -a AUTH, --auth AUTH Basic authentication user:password --header HEADER Custom header. name:value --hook HOOK Python callable that'll be used on every requests call
--json-output Prints the results in JSON instead of the default
format -n REQUESTS, --requests REQUESTS

结论ab和boom在功能上远不及multi-mechanize和Grinder等主力python性能测试工具，甚至还比不上庞大且扩能能力差的loadrunner。只建议在对单个中间件的基准测试时使用。 |
