first contentful paint (server rendering) (FCP)

First Contentful Paint(FCP) is a measurement of the loading speed of a web page. This characteristic value is about when the first image detail appears on the browser display when a web page is called up.

The First Contentful Paint is the time that elapses from the time a web page is called up until the first file display. The FCP time is determined after the connection between the web server and the browser is established and source code, script files, fonts, graphics, photos, and videos for the page content have been downloaded. The loading process for the web page that begins after this determines the FCP time.
