855: Fast Websites: The New Speculation Rules API

In this episode of Hasty Treat, the hosts dive into the new Speculation Rules API designed to boost website speed. This API improves techniques like preloading, prefetching, and pre-rendering, enabling developers to load resources before users even click on anything. While these enhancements can significantly improve performance, the speakers warn against overusing them, stressing the importance of balancing speed with potential increases in server costs and bandwidth usage. They also point out the limitations of relying solely on PageSpeed Insights scores, highlighting that the real focus should be on the actual user experience rather than just these metrics when assessing website performance.
