Web-based applications are an integral part of many companies, from e-commerce websites to customer service systems and tools for managing content. However, if they’re slow to load and don’t respond, the experience is frustrating for users. According to Google’s research that a one second delay in loading can result in a loss of conversions on a site or mobile application. And if you have an e-commerce site, customers will leave in just a few seconds if their shopping carts and checkout pages don’t load fast enough.
Optimizing web apps for performance has become more challenging than ever. In this article, we’ll break down some of the key concepts you should know in order to improve web app performance. We’ll also look at some of the main culprits in the performance arena – the factors that prevent your apps from running as smoothly as they ought to be.
The key to improving performance is to understand the user’s perspective. This is done by monitoring users in real time to assess how your app performs and what’s not working in relation to what you believe it should do.
A great way to do this is by using tools such as Chrome Lighthouse and PageSpeed Insights. These tools offer a quick snapshot of the performance of your web app on the devices of your customers, along with suggestions for improvement. Reduce the download size and bandwidth of your web application to increase its performance. GZIP compression of text-based resources, making images smaller, as well as CSS and JavaScript features like async/defer can all be useful.
