Microsoft says it has reached a “major milestone” in making its Edge browser faster and more responsive, after months of work to improve how quickly websites and features load.
According to the company, the latest Edge 137 update brings big performance gains, driven by Edge’s migration to a new architecture called WebUI 2.0. These improvements have been in progress since February 2025, and Microsoft claims they significantly enhance user satisfaction by reducing delays when browsing.
One of the most notable achievements is Edge’s global First Contentful Paint (FCP)—a measure of how fast content starts appearing on the screen—which has now dropped below 300 milliseconds. Microsoft points out that an FCP higher than 300–400ms can noticeably hurt how users perceive speed and responsiveness.
With this improvement, users can start interacting with websites much more quickly.
The company shared more details in a blog post, explaining that the switch to WebUI 2.0—described as a “markup-first architecture”—helps shrink code bundles and cut down on the JavaScript that runs when the browser loads its interface.
For example, the Settings page in Edge used to take about 0.394 seconds to appear. After moving to WebUI 2.0, the same page now loads in just 0.034 seconds, nearly four times faster. Microsoft measured this on a Surface Laptop 7 running Windows 11, equipped with a 12-core Snapdragon X processor and 32GB of RAM.
Beyond page loading, the company says average load times have improved by around 40% across a range of features, including Read Aloud, Split Screen, Workspaces, and Settings.
And there’s more on the way. Microsoft says it’s already working on additional performance upgrades for Extensions, Print Preview, and other parts of the browser. These updates are expected to roll out in the coming months.
