Speed with Delivery to the User
summary
Explains why measuring only server-side response time (e.g., “page generated in 300 ms”) is misleading and shows the real user-perceived load time depends on client-side factors. Uses concrete measurements to compare server rendering time with end-to-end browser load (example: 300 ms on server can become ~2.5 s in the browser for a 60–70 KB page) and argues for measuring delivery-to-user rather than just server timing.
