SpecificationNone Summary Skips the PreloadScan step of the browser to explore performance tradeoffs for pages with no sub-resource fetches. PreloadScan step of Chromium is implemented as a blocking step that benefits performance of pages with sub-resource fetches, via implementation of the speculative prefetch. However, for pages that don’t benefit from this step, i.e., for pages with no sub-resources, this is additional processing overhead with little benefit. For advanced web users who would like to benefit by reducing this overhead, this experiment provides a page-level control to disable the PreloadScanner. Data collected from this experiment could evaluate if a modified API or a different implementation of HTMLPreloadScanner would be helpful.

None Goals for experimentation Ongoing technical constraints None Debuggability None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?No Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?No No, since in this iteration we don’t have a web exposed API, and the valid OriginTrial token itself is currently used to trigger the feature. We plan to fully test the API via web-platform-tests once they are proposed.
