navCtrl.push creates new instance of page

I have a page in my app, where I read a lot of data on creation, and I did expect Ionic to reuse the page, when navigating to it later like this


but it looks like it creates a new instance each time, thus using memory, and using a lot of time to load the page.

I am using the tab starter template, and navigating between tabs is working as expected, but as soon as I open a new page, i can see that a new page is constructed, this executing both constructer and the ionView-events

My AboutPage, just for demo looks like this

  constructor(public navCtrl: NavController) {
    console.log("AboutPage Constructor called")

  ionViewWillEnter() {
    console.log("AboutPage ionViewWillEnter called")

  ionViewDidLoad() {
    console.log("AboutPage ionViewDidLoad called")

And each time i click on the button to navigate to about page I get this in the console

AboutPage Constructor called
AboutPage ionViewDidLoad called
AboutPage ionViewWillEnter called

Will I have to create the page my self, and then try to reuse that each time I want to open that page ?

I am on latest version of Ionic

Ok, this seems to be the intended way it should work according to

So does anyone have an idea of how to set


in an Ionic3 app (with lazy loading)?
