Microsoft Edge has achieved a significant milestone in enhancing the responsiveness and loading speed of its web browser interface, as announced by the company on Monday. The Redmond-based tech giant revealed that its dedicated efforts, which began in February 2025, have led to notable improvements in the loading speed of initial content—a crucial element influencing user satisfaction. As a result, users can now enjoy a more seamless web browsing experience with minimal delays.
A Faster Browsing Experience on Microsoft Edge
In a recent blog post, Microsoft outlined the updates that have contributed to the enhanced content loading speed of the Edge browser. The company proudly reported achieving a global First Contentful Paint (FCP) time of under 300 milliseconds. This metric is essential as it measures how quickly various user interface features within a web browser visually load. Microsoft emphasized that an FCP exceeding 300 to 400 milliseconds can negatively impact user satisfaction.
With this critical threshold now surpassed, users can engage with content more swiftly. Microsoft embarked on this initiative to refine multiple aspects of the browser’s UI back in February. Since then, it claims to have reduced load times by an average of 40 percent, alongside improved responsiveness in features such as Settings, Read Aloud, Split Screen, Workspaces, and more.
This remarkable progress has been made possible through the migration to WebUI 2.0, which employs a markup-first architecture designed to minimize the size of code bundles and JavaScript that executes during UI initialization. For instance, the Settings page in Edge previously took 0.394 seconds to load before the migration, but this time has been slashed to just 0.034 seconds afterward—an impressive nearly fourfold increase in speed. Both measurements were taken on a Surface Laptop 7 equipped with a 12-core Snapdragon X CPU and 32GB of RAM, running Microsoft Edge 137 on Windows 11.
Yet, the journey does not end here. Microsoft has indicated that it is actively working on further performance enhancements across additional features, including Extensions and Print Preview, with plans to roll these out in the coming months.
