1807359 - Pageload experiment: -O2, -Oz build flags

Status: RESOLVED DUPLICATE of bug 1831935

(Fenix :: Performance, defect)

Description

[Chris Peterson [:cpeterson]]

From github: https://github.com/mozilla-mobile/fenix/issues/7795.

edit: see https://github.com/mozilla-mobile/fenix/issues/7795#issuecomment-861569546 for what the next steps for this issue are.

Why/User Benefit/User Problem

Switching to the -O2 flag has pageload perf improvements, but increases apk size by ~6MB.

Need this experiment to measure tradeoffs.

What/Requirements

• [x] Stability experimentation on 3.2 1/22-1/27 w/ GV 74 Nightly
• [ ] A/B test on Firefox Preview Release (pending Phase 1): 1/27-2/14 w/ GV 73 Beta
• [ ] Decide which version of GV to use for upcoming releases
• [ ] Update GV version in AC right before 3.3 goes out

This experiment would be run in staged rollout through Google Play, because Mako doesn't have this capability. Johan is assisting with this.
Corey from the Data Science team is involved in analyzing the results for retention.

Acceptance Criteria (how do I know when I’m done?)

Data Science has results that allow us to make a perf decision.
