Status: ASSIGNED

(Core :: Performance Engineering, defect)

Attachment: screenshot

See attached screenshot. I noticed this while trying to generate PGO profiles locally, but it seems we get the same thing on CI from looking at logcats. I see a bunch of these messages for each subtest:

GeckoSession: handleMessage GeckoView:LocationChange uri=http://10.0.2.2:8888/js-input/webkit/PerformanceTests/Speedometer3/resources/react-stockcharts/build/index.html?type=svg

but the URIs do not repeat. and then the final one:

GeckoSession: handleMessage GeckoView:LocationChange uri=http://10.0.2.2:8888/js-input/webkit/PerformanceTests/Speedometer3/resources/perf.webkit.org/public/v3/Speedometer3/resources/perf.webkit.org/public/v3/#/charts/?since=1678991819934&paneList=((55-1974-null-null-(5-2.5-500)))

which matches the screenshot showing it is on React-Stockcharts-SVG in the first iteration, and failed to load perf-dashboard.

We should fix this, and hope that training PGO being trained on the full speedometer 3 run rather than just nearly a single iteration improves performance.

It seems we already encountered this same issue for desktop PGO profile generation in bug 1867581

I was able to fix this by replacing mozhttpd with python's httpserver.
