apache mpms

Choosing the right Multi-Processing Module (MPM) for Apache HTTP Server—Prefork, Worker, or Event—affects performance and scalability. Prefork is simple and stable, ideal for non-thread-safe applications but less scalable. Worker uses threads, offering better efficiency and scalability. Event, an advanced version of Worker, supports high concurrency and efficient keep-alive connection handling, ideal for high-traffic sites. Each MPM serves different server needs and environments.
