We have a perf test in CI called shopify-applink-startup. On the A55, we are currently 33% behind Chrome:
Chrome: ~3500ms
Firefox: ~2500ms

This test simulates the "app link" scenario: No Firefox process is running, and the user taps a link in some other app, so that Firefox starts up and loads the tapped link. So this scenario includes Fenix startup, GeckoView startup, and page load.

(The test name has "shopify" in the name because it's currently using a live site which is a shopify site template, specifically https://theme-crave-demo.myshopify.com/ .)

This bug tracks improving our number.

(todo: add instructions for how to run this test locally)

I have succeeded running locally on an attached pixel8 with

python3.11 python/mozperftest/mozperftest/runner.py --flavor custom-script --app fenix testing/performance/mobile-startup/cvne.sh --perfherder

python3.11 is the maximum supported version at the moment
