INP
A responsiveness metric based on the latency of user interactions throughout a page visit.
INP
Interaction to Next Paint (INP) evaluates page responsiveness using interaction latency observed across a visit. It includes input delay, event-handler work, and the time until the browser presents the next frame.
Improve INP by breaking up long tasks, reducing JavaScript execution, limiting synchronous rendering work, and keeping interaction handlers focused.
