Mark GoldsteinGUEST
Yeah, so I shared a little bit of the challenges previously that are related.

Mark GoldsteinGUEST
But in terms of optimizing that are related to that, instrument first has helped us tremendously.

Mark GoldsteinGUEST
Being able to measure your app and have telemetry enables you to have clarity on what to optimize, what to fix.

Mark GoldsteinGUEST
So things like cold start, warm start, time to time to interaction for the Build time optimizations for development is incredibly rewarding as well, especially if you have a larger team setting up something like a remote build cache and leveraging Expo Fingerprint to decide when you can leverage a build cache build for your development or your agent, or when you actually need to rebuild is incredibly powerful.

Mark GoldsteinGUEST
We found that even with a eight plus year old app code base like us, Only 5% of pull requests actually change the fingerprint and require a rebuild.
