Benchmarking and performance tuning of Apache
In this recipe, we will learn some performance tuning configurations that may help to squeeze out the last bit of performance from the available hardware. Before diving into performance tuning, we need to evaluate our servers and set a benchmark which can be used to measure improvements after any changes. We will be using a well known HTTP benchmarking tool, Apache Bench (ab). Various other benchmarking tools are available and each one has its own feature set. You can choose the one that best suits your needs.
Getting ready
You will need two systems: one with the web server software installed and another to run Apache Bench. You will need root access or access to an account with similar privileges.
