In a follow-up to a change I made to improve webp decode performance in Chrome on Android Egor pointed out that it might be useful to have a regression test for this if possible [1]. I don't have any familiarity with this system, so I was curious what the current state of things was.

Salient points from the bug:

> Are these benchmarks on the perf dashboard so that regressions are automatically analysed?

No. I don't believe decode performance for images is being captured currently. We are tracking webp performance during development and at release, but it's true that won't catch a regression due to e.g., build changes.

...

Feel free to create a bug for continuous regression testing if you need it. telemetry@chromium.org group would have some ideas how to make it in a maximally blessed way. I guess that would be like one of our raster benchmarks, but there is always a risk of seeing deprecated ways to write a benchmark...
