“Premature optimization is the root of all evil but lack of optimisation is the root of outages.” Table of Contents Introduction Architecture Overview Why Optimisation Is Required Nginx Optimisations & Parameter Calculations PHP-FPM Optimisations & Parameter Calculations MySQL Optimisations & Parameter Calculations System-Level Optimisations (Linux) Practical Example: Small vs Medium vs Large Server Interesting Facts & Statistics FAQs Key Takeaways Conclusion 1. Introduction Modern web applications rely heavily on the Nginx + PHP + MySQL (LEMP) stack. While default configurations work for testing, they are not suitable for production traffic. Optimisation ensures: Faster page load time Better concurrency handling Lower memory and CPU usage Higher stability under load This document explains what to optimise, why to optimise, and how to calculate parameters practically. 2. Architecture Overview A typical request flow: Client sends HTTP request Nginx handles connection &am
