This one is weird, the ref vanishes at the point of the alert. I'm inclined to suspect the ref should have moved at the same time given the bots can't find a regression. +sullivan@ what do you make of this?

+martiniss, mikecase: Wasn't there a config mixup on the webview perfbots lately, where they ran chrome instead of webview? Since we don't have webview ref builds, and ref builds are showing up in the graph, I think this is because we fixed the glitch?

re #6 Yeah, not super familiar with current situation. But I think all the "webview" perf results from the past few weeks were really testing Chrome. Also, its not 100% fixed yet, as all of the perf devices were also flashed to non-AOSP builds of Android this past month which means, even if you specify --browser=android-webview, it won't actually test the webview being installed. Hopefully we can get this all cleaned up next week.

This alert was found before M-60 branched. Closing as WontFix as this is believed to either be invalid or non-reproducible. |
