FCP is a metric that Google introduced in Chrome in 2017 to measure how long it takes for a browser to render the initial DOM content after a user navigates to a page. For PC web browsers, Google has set the scoring criteria as 'fast' for 0-900 ms, 'medium' for 900-1600 ms, and 'slow' for anything over 1600 ms.

Microsoft said, 'Industry research shows that delays of more than 300-400 milliseconds for initial content display can significantly impact user satisfaction. With an FCP of less than 300 milliseconds, the most frequently used browser features will appear almost instantly, allowing users to access content faster.'

Microsoft claims that 13 different browser features have had their loading times reduced by an average of 40% and improved responsiveness. Examples of the browser features that have been made faster include:

·setting

・Split screen

Workspace

Starting with Microsoft Edge 132, released in February 2025, Microsoft is transitioning to the 'WebUI 2.0' architecture to achieve significant performance improvements in multiple Edge features. This WebUI 2.0 architecture will minimize the amount of JavaScript code executed during UI initialization.

Microsoft has released the following video that shows just how much faster the Settings UI actually loads in Edge.

'We're proud of these advancements, but our work isn't done yet. You can expect further performance improvements in even more features, including print preview and enhanced features, in the coming months,' Microsoft said.
