PHP-FPM is the process manager that sits between Nginx and your Laravel application. Every web request that reaches your server ultimately becomes a PHP-FPM worker processing your code. How many workers you run, how much memory each one can use, and how the process manager spawns and recycles them directly determines your application's throughput, response time, and stability. Most Laravel applications run on default PHP-FPM settings. These defaults are designed to be safe for any application on any server, which means they are optimal for nothing in particular. Tuning PHP-FPM for your specific application and server resources can double your throughput or cut your response time in half. This guide explains every important PHP-FPM setting, how to calculate the right values for your Deploynix-managed server, and how to monitor the results. How PHP-FPM Processes Work When PHP-FPM starts, it creates a master process and a pool of worker processes. Each worker can handle one request at a t
