nativescript-angular: Very slow bootstrap after Angular RC-5 upgrade (>3 seconds)

I have detected that since the last update of angular (NG 2.0) the bootstrap of the application slows down dramatically (about 3 second of white screen after the splash screen on my laptop and even worse on the devices). Check out the log/code below running on the emulator.

I’m wondering which alternatives do I have to improve the startup speed ?

Check this log fragment:

The bootstrapping took 3 seconds:

• Bootstrap started: Tue Sep 27 2016 05:59:12 GMT-0300 (UYT)
• Init started: Tue Sep 27 2016 05:59:15 GMT-0300 (UYT)

Basically here is the code that produce the log:

import { platformNativeScriptDynamic, NativeScriptModule } from "nativescript-angular/platform";
import { AppModule } from "./app.module";

console.log("Bootstrap started: " + new Date());
platformNativeScriptDynamic().bootstrapModule(AppModule);

export class AppComponent implements OnInit {

    constructor(private _router: Router ....) {
        _translateService.setDefaultLang("en");

         // the lang to use, if the lang isn't available, it will use the current loader to get them
        _translateService.use(AppConfig.USER_LANGUAGE);
    }

    ngOnInit() {
        console.log("Init started: " + new Date());
        this.registerUserIfNotExists();
        ...
        console.log("Init finished: " + new Date());
    }

And here the the current module (as an example of dimension of the app):

    ],
    providers: [

        GoogleService,
        ImageService,
        PurchaseService
    ],
    bootstrap: [ AppComponent ]
})
export class AppModule {}

Let me add that I packaged the application with webpack recently (expecting this might cause an improvement) but basically remains the same.
