Developer discloses how Never-Slow Mode on Chrome works

how Never-Slow Mode work

Google Chrome, which has always pursued speed, will not give up and continue to increase the loading speed. Of course, taking up more hardware resources is also a headache for Google. How to improve the loading speed and reduce resource consumption is Google’s goal, so the Never-Slow Mode (a.k.a. Slightly-Fast Mode) also came into being.

It seems that Google Chrome should be ready to launch the Never-Slow Mode, so now the details about the model and the development standards have been announced.

Never-Slow Mode (“NSM”) is a mode that sites can opt-into via HTTP header. For these sites, the browser imposes per-interaction resource limits, giving users a better user experience, potentially at the cost of extra developer work. We believe users are happier and more engaged on fast sites, and NSM attempts to make it easier for sites to guarantee speed to users. In addition to user experience benefits, sites might want to opt in because browsers could providing UI to users to indicate they are in “fast mode” (a TLS lock icon but for speed).

At present, the standard release needs to wait for the website developers to transform and adapt. The first thing to be tested is still the Google Chrome Canary. The current experimental function of the speed mode is already available in the Canary version, but there is no change after the temporary opening, so there is no way to experience it.
