In this tutorial, we will explain how to tune and optimize your Nginx configuration file to help speed up your website’s performance. Nginx is a fast, lightweight, and high-performance web server in charge of serving at least 40% of all websites globally. When compared to other web servers, Nginx is primarily known for its speed, with it capable of handling thousands of concurrent connections with ease. Nginx can also be used as a load balancer, a reverse proxy, and an HTTP caching server. It uses little resources and is ideal for delivering static content. To help further improve performance, Nginx has a built-in caching system that allows dynamic requests to be cached directly on the server for future requests, thereby reducing the load on your CPU and system in general.
