But while it’s been around for a long time, it’s not one of the best-performing options. Prefork is a very well-known MPM for Apache. There are three popular MPMs commonly used in most Apache web servers: Prefork, Worker, and Event. MPMs are accustomed to handling multiple requests in parallel by using a threaded approach and running on multiple CPU cores. Knowing which Multi-Processing Module (MPM) your Apache installation is using will make it easier to identify which parameters you need to monitor.
The Three Most Popular MPMs Used in Apache In this blog post, we’ll go through the key Apache server metrics you should track and the best performance monitoring tools to help you set up an efficient monitoring and alerting strategy. Regularly monitoring the performance can help you avoid these issues. It’s a well-known fact that with high traffic, the performance of Apache web servers can take a hit, experiencing bottlenecks as your traffic scales up, which will lead to delayed responses. Because you can easily customize it through modules, it has become the go-to choice of both individuals powering their personal blogs and enterprises running high-traffic websites and web apps. The Apache HTTP Server (httpd) is a widely used, open-source web server application.
