The Art of Predictive Prefetch

Browser hints like prefetch enable you to get critical resources in advance and save valuable (next) render time. These speculative optimizations integrate the developers assumptions about the users route. Speculative pre-fetching can be wasteful due to incidences of fetching resources that will never be used. Leaning on advances in machine learning and analytics data allows us to significantly increase the efficacy of our fetches. Let’s explore techniques that move predictive prefetching from …
