There are a few things I'd like to try:

• Enable gradle build cache
• Enable gradle configuration cache
• Enable gradle parallel task execution
• Enable ccache

[roryabraham]

In order to be methodic and quantitative with these changes, I'll be using ./gradlew build --scan to generate detailed build scan reports.

@roryabraham I’m very interested in this task and confident in my ability to deliver high-quality results. I'd love to take on this project—are you ready to assign it to me?

Build scan for a clean ./gradlew assembleDebug (note: next time I should do active arch only, because that's what we do in dev)

[roryabraham]

Another clean build scan, this time only one arch: https://scans.gradle.com/s/4apezfw7xtotm

Build command was: ./gradlew assembleDebug -PreactNativeArchitectures=arm64-v8a --scan

A build scan with only this diff:

Adding the org.gradle.caching=true does not appear to be worth it, because:

• It has no effect on the configuration phase, which consistently takes about 10 minutes while the build phase takes about 1 minute w/ parallel enabled.
• Even a cached build seemed to take about a minute, but populating the cache takes longer
