AB is a tool for benchmarking Apache Hypertext Transfer Protocol (HTTP) server. It is designed to give an impression of how current Apache installation performs. More specifically it shows how many requests per second Apache installation is capable of serving.
This post is mostly a self reminder. I have updated my system to Ubuntu 14.04 and that leads to set up almost everything once again. I observed that I forgot few key steps about setting this up. So it’s better to note it down so that next time I don’t have to find again.
