In web application development, website performance optimization is an endless yet quintessential task. One hundred milliseconds on the web can make a significant difference, and 1 second is a lifetime. Numerous studies have shown that faster website loading speeds are associated with better conversion rates, user retention, and organic traffic from search engines. Most importantly, they provide a better user experience.
In this article, I will share tips to speed up a web application and serve customers faster. In recent times, web developers have been creating more and more web-based applications, and Django is one of the most popular python-based frameworks. Django is relatively easy to use and flexible. However, this flexibility can slow down the application.
How to Optimize Django Website Loading Speed
A lot of the time, when people talk about how to improve website speed, they focus on front-end optimizations. However, optimizing the website hosting server, images, JavaScript and CSS files, web fonts, and a web server(running on NGINX or Litespeed) are just a few factors that can impact your website speed. Follow the steps below to improve or speed up the website loading speed.
