As a result of the processing of key components, the average formation time of the first content (FCP) is now less than 300 ms. This is a critical threshold: Delays over 300-400 ms significantly reduce the comfort of use, research notes.
To gain acceleration, Microsoft rejected React in favor of its own WebUI 2.0 architecture based on local web components-HTML forms and CSS. This reduced the load time on average 40% of 13 main functions.
A particularly impressive development is noticed in the Settings section: now it opens 4 times faster than the old version. The functions of the work areas are also accelerated. Even on weak devices.
In 2025, acceleration will be achieved to other sections: Preliminary imaging of the gasket, extensions panels, etc.
