Microsoft has revealed a major advancement in enhancing the speed of the user interface of its Edge browser.
Edge now renders the initial portions of a website in less than 300 milliseconds, according to the tech giant's First Contentful Paint (FCP) metric.
With this update, users should experience a faster and more responsive browser.
Microsoft claims that industry research indicates that user satisfaction can be greatly impacted by waiting more than 300 to 400 milliseconds for initial content.
The company has been working to improve Edge's performance by moving its user interface to a faster architecture known as WebUI 2.0 in order to address this problem.
This architecture minimises the amount of JavaScript code that runs during initialisation and minimises the size of code bundles.
The enhancements come after Microsoft previously increased performance by 40% for specific features like history, downloads, and the creation of new private browsing tabs.
Since then, the business has improved the performance of 13 more browser features, such as settings, split screen, and read-aloud.
Notably, the read-aloud function now offers more fluid playback, and the split-screen feature now offers "near-instant navigation and fewer loading delays."
In the upcoming months, Microsoft intends to add more Edge performance enhancements, such as Print Preview and Extensions.
Given that Edge currently holds a smaller market share than Google Chrome, these improvements may encourage users to switch.
