Google's Abandoned 'Never-Slow Mode' Feature Would Have Radically Changed Chrome
Google's Chrome browser has been the primary web browser for many users, including myself. While it's not perfect, its handy browsing tools and deep integration with the wider Google ecosystem make it a popular choice.
In 2019, Google was working on a radical feature called 'Never-Slow Mode,' which aimed to ensure that Chrome would never slow down under any circumstances, unless the internet connection is poor. This feature would have blocked large scripts and assets like fonts and images based on size if they exceeded predefined limits.
The proposed limits were:
- Per-image max size: 1MiB
- Total image budget: 2MiB
- Per-stylesheet max size: 100KiB
- Total stylesheet budget: 200KiB
- Per-script max size: 50KiB
- Total script budget: 500KiB
- Per-font max size: 100KiB
- Total font budget: 100KiB
- Total connection limit: 10
- Long-task limit: 200ms
The feature was met with both excitement and criticism, with some arguing that it could break content when implemented. Despite the potential risks, I believe Google should have at least given users a flag to enable the feature for those who want it.
