Ask questionsbundleReleaseJsAndAssets slow for react-native 0.60 / node v12 combo
I believe I am using the most recent metro, or very near it, as this is with react-native 0.60 rc3 which has a 0.54.1 version of metro in package-lock.json after using react-native cli to do an app init using the RN0.60RC3 template
What is the current behavior?
For some reason, which this combination, it is taking a great deal more time to generate the release bundle then with any other combination of react-native 0.59 vs 0.60 and node 8, 10, 11 or "node" (currently 12.5)
I'm testing them all as part of the jetifier project in CI and this was noticeable.
You can see all an identical job but with node 11 here: https://travis-ci.com/mikehardy/jetifier/jobs/212061152 - it's 5 minutes different

@mikehardy it's an issue with node 12.5. Downgrade to 12.4 or earlier and the issue goes away.
I agree it's strange it only surfaced with RN 0.60, but it's fine with RN 0.59
