Microsoft Edge Achieves Major Milestone in Browser Performance
Microsoft has announced a significant improvement in the responsiveness and loading speed of its Edge browser’s user interface. The company achieved a global First Contentful Paint (FCP) of below 300 milliseconds. This is a key metric that measures how quickly UI features visually load.
Key Improvements:
- 40% average reduction in load times: Across 13 core browser features, including Settings, Read Aloud, Split Screen, and Workspaces.
- Faster Settings page loading: Load times reduced from 0.394 seconds to 0.034 seconds, making it almost four times faster.
- Improved responsiveness: In features like Read Aloud, Split Screen, and Workspaces, providing a smoother user experience.
How Achieved:
- WebUI 2.0 architecture: A markup-first approach minimizing code bundle size and JavaScript code during UI initialization.
- Ongoing efforts: Microsoft started improving Edge’s performance in February 2025, focusing on reducing load times and enhancing responsiveness.
Future Updates:
- Additional performance improvements: Coming soon for features like Extensions and Print Preview.
- Continuous development: Microsoft aims to maintain Edge’s reputation as one of the fastest browsers available.
