I was trying to check the performance of my Xamarin application. While I was reviewing the application, sometimes I felt the application was slow when the form opened and closed.

Here is the output of the logs.

You keep pushing new pages onto the navigation stack. You need to use pushmodal to open a modal page and then

await Navigation.PopModalAsync()

to remove it from the stack. Otherwise you just keep opening new pages and they consume memory.
