Performance - Pages vs Pop-ups

Question
1

Considering overall architecture of my app. What I find is that moving from page to page is slow, where as moving from page to pop up, and pop up to pop up is really fast.

Wondering the background as to why this is and if there are any performance issues with the pop ups that I am overlooking, i.e. once I start scaling up?

Any insights welcome

With a lot of pop-ups, your app will initially load slower (once, which you can mitigate with a load screen), but move faster as users interact with each pop-up. With individual pages, you will have the load time for each page slowing users down vs pop-up experience, with unavoidable wait times.
