Basic information

1591725 found that building Gecko for Android using the -O2 flag improved a number of different performance metrics. We should identify whether there are other libraries we build for Android that could be optimized for speed by using a different compiler flag. The primary metric that we'd hope to move is app (e.g., Fenix) startup time.

Priority: -- → P1

Not likely we'll find much else; most things not part of gecko aren't c++. Glean is IIRC rust

Priority: P1 → P2
Blocks: 1604930

The performance calculator doesn't apply well to this bug.
Low because the measured impact of optimizing gecko was minimal when measured via telemetry.
