Can't have my Ionic app starting in less than 5.5 seconds

Ionic Framework ionic-v3
1

Hi everyone!
I think I’ve implemented all existing recommendations to improve Ionic bootstrap time, but I still can’t have my app starting under 5.5 seconds on Android.

Things I’ve done:

  1. –prod flag in building
  2. updated ionic platform to the latest version
  3. lazy loading

My app is pretty small: just 9 pages and one services.

I’d like just to check if I’m missing something.

Thanks!

  • What device are you testing on?
  • What is your ionic info output?
  • Native functionality via Cordova plugins?

Did you remote debug the problem on the device already? Follow these instructions here to debug the problem in Chrome dev tools: https://ionic.zone/debug/remote-debug-your-app#android Look at the console and network tabs for errors.
