Speed Kit is a website acceleration software designed to improve the page speed of highly dynamic ecommerce websites like the ones Decathlon runs. Using a combination of browser and cloud technologies together with innovative caching algorithms, Speed Kit helps Decathlon to significantly improve Time to First Byte (TTFB) as well as Largest Contentful Paint (LCP) across all devices. This is leading to an improved user experience and in turn increases various ecommerce KPIs as well as top-line revenue.
