Google Chrome is getting a real-time webpage performance overlay

Google Chrome is getting a new browser heads-up display (HUD) that displays performance metrics about the web pages you are visiting.
 
In April, Google introduced a new initiative called Core Web Vitals that measures a webpage's performance and user experience metrics that are needed to offer a good user experience when browsing a website.
 
The Core Web Vital metrics that Google is currently measuring is Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), which are described below.

• Largest Contentful Paint (LCP) measures when the largest element in a browser's viewable screen becomes visible. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading.
  
• First Input Delay (FID) measures the time from when a user first interacts with a page to when the browser is able to respond to that interaction. To provide a good user experience, pages should have a FID of less than 100 milliseconds.
  
• Cumulative Layout Shift (CLS) measures how much visible content shifts in the viewport as well as the distance these elements are shifted. Common reasons for CLS is when ads are displayed that push down visible content. To provide a good user experience, pages should maintain a CLS of less than 0.1.
  

In May 2021, Google will utilize a web site's Core Web Vitals metrics as a ranking factor in the Google search engine algorithms.
 
To help users analyze these metrics on web pages, Google released a Chrome extension named Web Vitals that displays an on-screen HUD with performance metrics for web pages you are visiting.
