Hmm, I doubt that this will help. Can you give an example? I also want to note that the modal window also loads slowly and it does not apply to navController.
Certainly when I’ve been playing with your app on my devices it feels pretty good.
Are you go above and beyond?
I found my problem here https://github.com/ionic-team/ionic/issues/6621. I understand the problem has not yet been resolved?
Did you ever fix this? The first time I push a page it’s also slow but the next times they’re fast
