What is FID in concern with Page Speed?

[Maria Jonas]

First input delay; which measures the time between when a user first interacts with your site (i.e., when they click on something) to the time the browser is able to respond to the interaction.

Time to interactive (TTI) is a metric that measures how long it takes your app to load and become capable of quickly responding to user interactions, and First Input Delay (FID) is a metric that measures the delay that users experience when they interact with the page while it's not yet interactive.

Hi Friends,
First input delay; which measures the time between when a user first interacts with your site (i.e., when they click on something) to the time the browser is able to respond to the interaction.

First Input Delay (FID) is an important, user-centric metric for measuring load responsiveness because it quantifies the experience users feel when trying to interact with unresponsive pages—a low FID helps ensure that the page is usable.

FID (First Input Delay): This type of metric becomes interactive when a user is doing some kind of activity. The time when a user first interacts with the site, this metric tracks the delay between the time a user interacts and the browser responds to the interaction.
