I've tried anything today without luck (changing node version, typescript from 2.0.3 to 2.0.9, etc.):
* conference app ... it has like 8 pages: starts in 5-6 seconds
* my full app... like 30 pages: 10-12 seconds
* if i remove all the pages and shrink down the starting time reduces
Of course building without --prod or --aot makes the boot even longer: 32 seconds.
Removing the plugins or Xwalk has no effects.
I've putted a new date() in index.html and used this to calculate the time of the execution of the app constructor and of the ready() event.
But no worries i've created a nice pure CSS animated preloader to engage the user meanwhile
