This sounds like a good candidate to include in Talos and other tools that measure pageload related performance. thinking more, having this in our frameworks (like web-platform-tests, mochitest, reftest) would be nice to keep reference to, it might be more complicated to store that data long term, but maybe setting a baseline and failing a test if it crosses a 2x threshold _______________________________________________ dev-servo mailing list dev-servo@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-servo
