Long Boot Time for Ionic 1 Application

We have an application which is entirely build using Ionic 1 and ES6 along with Babel and Webpack. The problem is that application’s Boot time is very slow. It almost takes 10 to 12 seconds to and the app is stuck in the Splash Screen until that time. I have tried everything possible but nothing changed. On the other hand I see that platform.ready takes like forever to load. It almost takes 10 seconds. I don’t want to change the framework to 2 and above. Is there some way in which we can optimize it? Even few Seconds of Optimization can save things for us.

Start with the basics:
What is your ionic info output?
What device are you testing this on? OS? OS version?

Its given below Sujan

Your system information:

Cordova CLI: 7.0.1
Gulp version: CLI version 3.9.1
Gulp local:
Ionic Version: 1.3.1
Ionic CLI Version: 1.4.0
Ionic App Lib Version: 0.0.16
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Mac OS X Yosemite
Node Version: v6.11.4
Xcode version: Xcode 9.0.1 Build version 9A1004

Uh wow. You should really update this. Ionic v1 projects also work with the current CLI.
This will give much better ionic info output that will tell us a lot more.

You might also want to update this, there should be newer versions available.
