Nginx Advanced Configuration and Performance Tuning

Nginx has become the web server of choice for high-traffic websites, serving over 40% of the top 10,000 websites globally. Its event-driven architecture and low memory footprint make it ideal for modern web applications. This guide explores advanced Nginx configuration techniques and performance optimization strategies for production environments.

Understanding Nginx Architecture

Nginx uses an asynchronous event-driven architecture, fundamentally different from Apache’s process/thread-per-connection model. This design enables Nginx to handle thousands of concurrent connections with minimal memory usage^[1].
