Microsoft claims Edge browser performance has been significantly improved

In February last year, Microsoft announced plans to transition to the WebUI 2.0 platform on the Edge browser. This process promises to significantly increase web browsing performance, while reducing the loading time of different parts of Edge. Recently, Microsoft continued to update many new performance improvements on its browser.

In a new blog post, Microsoft outlines the latest changes to the browser's "core." Thanks to the development effort, the company has achieved a major milestone: reducing First Contentful Paint (FCP) time to under 300 ms (FCP measures how quickly parts of the user interface load). Microsoft claims that wait times above 300–400ms severely impact the user experience, and dropping below 300ms makes everything appear almost instantaneous, bringing the browser up to modern web standards and outperforming the competition.

Since the February 2025 update, Microsoft has reduced load times by an average of 40% across 13 different browser features like Read Aloud, Split Screen, and Workspaces. The company also released a short video demonstrating the benefits of WebUI 2.0 in the browser settings:

The transition to WebUI 2.0 is ongoing, which means more parts of the browser will continue to be updated. In the coming months, Microsoft is committed to moving more Edge components to WebUI 2.0, including Print Preview, Extensions, and other commonly used parts.

It's great to see Microsoft focus on the important aspects of the browser and improve performance instead of just annoying users with ads and pop-ups. With the latest performance upgrade, the Edge browser now runs much smoother than before.
