How to Optimize Web App Performance

Web-based applications are an integral part of a lot of companies. They range from e-commerce sites to content management systems and customer service systems. If they’re slow to load or do not respond and unresponsive, it can be a major inconvenience for users. A single second delay in load time can result in lost conversions for a website or app according to Google’s study. And if you have an online store customers can leave in a matter of seconds when their shopping carts as well as checkout pages aren’t loading fast enough.

As the development and deployment of web applications is constantly evolving making it more difficult to optimize them for performance is more difficult than ever before. In this article, we’ll explain the fundamental concepts you must understand to improve web app performance. We’ll also discuss the biggest problems in web performance – things that can stop your apps running smoothly.

The key to improving performance is understanding the perspective of the user. This requires monitoring the user’s behavior to see the performance of your application and what’s missing as opposed to what you think it should be doing.

This can be done by using tools like Chrome Lighthouse or PageSpeed Insights. These tools provide an overview of your website app’s performance across your users’ devices, with practical suggestions for improving it. Reduce the size of downloads and bandwidth of your application to boost its performance. Utilizing GZIP compression for text-based resources, minimising image files, and making use of CSS and JavaScript features such as async/defer could all aid.
