In today’s fast-moving digital world, speed matters more than ever. Users expect websites to load instantly - and search engines like Google reward fast, smooth experiences.

A slow website doesn’t just frustrate visitors; it can negatively impact search rankings, traffic, and conversions. Site speed is also closely tied to how efficiently your application handles requests, authentication, and data flow. For example, secure yet lightweight authentication plays a role in performance, which we’ve explained in our blog OAuth and JWT Explained Simply: A Beginner-Friendly Guide for 2026.
