React native run android terribly slow

I have a decent working laptop here. But the build speed seems to be intolerable to me. It takes me around 3 minutes for a debug mode build in android and 7 minutes for release mode build in android for my application. Was it a matter related to certain release of react-native or nodejs? Or what exactly causes the slow build?

The app does not have hermes/proguard enabled. It’s the similar timing despite i build on simulator/real device.

At least it doesn’t seem “OK” for me. 3 minutes compilation is already long and 7 minutes compilation is very ridiculous to me.

Note: Mind to share what build time u all use as well?

1) npx react-native run-android (takes 3 minutes)
2) npx react-native run-android --variant=release (takes 7 minutes)

React Native version: System: OS: Windows 10 10.0.18363 CPU: (8) x64 Intel® Core™ i7-8650U CPU @ 1.90GHz Memory: 15.41 GB / 31.88 GB Binaries: Node: 12.9.1 - C:\Program Files\nodejs\node.EXE Yarn: 1.21.1 - C:\Program Files (x86)\Yarn\bin\yarn.CMD npm: 6.10.2 - C:\Program Files\nodejs\npm.CMD IDEs: Android Studio: Version 3.5.0.0 AI-191.8026.42.35.6010548 npmPackages: react: 16.9.0 => 16.9.0 react-native: 0.61.5 => 0.61.5

Steps To Reproduce

1. npx react-native run-android (takes 3 minutes)
2. npx react-native run-android --variant=release (takes 7 minutes)

Describe what you expected to happen:

• Expect to takes around 1-2 minutes at most
