*Specification* *No information provided* *Summary* Expose measurement data regarding speculative loads (preloads, prefetches and prerenders) as part of a newly exposed `performance.getSpeculations()` method. That would enable developers to measure the efficacy of various speculative loading strategies and adapt them accordingly. *Blink component* Blink>PerformanceAPIs <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EPerformanceAPIs%22> *Web Feature ID* Missing feature *TAG review* *No information provided* *TAG review status* Pending *Origin Trial Name* Speculative Load measurement *Goals for experimentation* None *Chromium Trial Name* SpeculationMeasurement *Origin Trial documentation link* https://github.com/WICG/speculative_load_measurement#speculative-load-measurement-api *WebFeature UseCounter name* kSpeculationMeasurement *Risks* *Interoperability and Compatibility* *No information provided* *Gecko*: No signal *WebKit*: No signal *Web developers*: No signals *Other signals*: *WebView application risks* Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? *No information provided* *Reason this experiment is being extended* I'd like an extension for the trial for a couple of reasons: * Some partners are just able to start experimenting now, and their input would be valuable. * For most of the trial, we had a very significant bug in navigation reporting. The fix just landed in stable, so it seems worthwhile to continue the experimentation. Beyond that, since the milestone cadence changed mid-trial, The trial can actually run until M158 before the initial 6 months run out. *Ongoing technical constraints* *No information provided* *Debuggability* *No information provided* *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 *Flag name on about://flags* *No information provided* *Finch feature name* *No information provided* *Non-finch justification* *No information provided* *Requires code in //chrome?* False *Tracking bug* https://issues.chromium.org/issues/481590676 *Estimated milestones* Origin trial desktop first 150 Origin trial desktop last 155 Origin trial extension 1 end milestone 158 *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5118840377835520?gate=5091372532105216 *Links to previous Intent discussions* Intent to Prototype: https://groups.google.com/a/chromium.org/d/msgid/blink-dev/CAOmohSJA9q57gnHFyJ1WqUUJi2AX5UCmtDM50URp9hjx3J4WJg%40mail.gmail.com Intent to Experiment: https://groups.google.com/a/chromium.org/d/msgid/blink-dev/CAOmohSKBXF5hKYn9Lp6AvyEnESrBSvruyCVcHVcJae-56dcYNQ%40mail.gmail.com This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
