Speed Index

Checks how quickly the contents of the page are visibly loaded.

The Speed Index is an overall score, expressed in milliseconds, that indicates the average time that the different parts of a webpage are displayed. A low score (under 3400ms) means that the different parts of the page load quickly. A high score (over 5800ms) means that the website loads slowly.

For more information, please read the documentation on Web.dev.
