Help needed about using httperf in linux

Could anyone give me a full guideline on using httperf in linux. I
need a guideline from installing httperf to sending test report to
developers. I watched two videos from bestechvideos.com

and googled little bit for httperf but couldn't find anything very
helpful. Probably im missing something. So need your help.

Thanks in advance
