Are you worried about your Apache server performance? Okay let’s talk about Apache Multi-Processing Modules (MPMs). There is a documentation for Apache MPM but who has got time to read the documentations. Let’s talk in simple plain english about Apache Multi-Processing Modules (MPMs). All you need is 15 mins to learn Apache MPMs(happy-face).
The MPMs are used to change the basic functionality of the web server. It’s possible due to Apache’s modular design. The MPM, or Multi Processing Module, you use is responsible for just about the entire HTTP session. Starting from listening on the network, taking requests in and most importantly, how to handle those requests. With the MPM you use Apache’s behaviour will change. Apache offers three MPMs to choose from; Prefork, Worker, and Event. You might be wondering which MPM module you should choose. Answer is right below.
