How to improve PrestaShop performance

Browsing on mobile devices surpassed browsing on desktop computers for the first time in 2016. Consumers are spending more and more time on smartphones and tablets to make purchases or subscribe to services, and this trend is only expected to increase. With mobile devices, the user experience and performance of e-commerce sites have become more important for businesses.

Mobile internet users pay a lot of attention to loading speeds. The mobile browsing experience can be frustrating if the e-commerce site is slow, especially if the page’s elements shift during the rendering of the page. Lighthouse and Google have introduced new parameters, among which the Cumulative Layout Shift (CLS) is surely the most important. These parameters introduce the concept of Web Vitals (announced in 2020) and are now more important than even Time to First Byte (TTFB), which is basically the time it takes the server/host to send the first byte to the visitor of a web page.

Each metric introduced by Google with the Web Vitals concept is key to the user experience, namely: loading, interactivity and visual stability.

Lighthouse: Web Vitals


These days, an e-commerce site’s loading speed is one of the main technical elements to be taken into consideration. Reductions in loading times equal not only better organic indexing, but they allow you to manage more simultaneous visits. The majority of e-commerce sites in PrestaShop have very high loading times (especially regarding TTFB) for a number of errors oftentimes associated with DIY. It’s not always enough to have an excellent Prestashop host or cache systems like Varnish. Rather, it’s important to optimize PrestaShop and its modules in order to significantly reduce loading times, keeping in mind the very limits of the HTTP 2.0 protocol. Increasing the server’s hardware resources is often thought to be enough, or that it’s enough to simply increase the engine’s horsepower to make it go faster. However, with race cars, in order to get the best performance, you need to balance every aspect, starting with the weight of the vehicle.
