Difficulty troubleshooting performance issue

Question

I have a main page in an app that has significant issues when the page is navigated to. I finally narrowed the issue when I added a static class that can be used to write trace information, and time elapsed to the debug out put. I have discovered that when this main page of the app is navigated to (always via hardware back, or nav.goback()) has a greater than 4.5 second delay between the OnNavigatedTo and the Loaded event. At that point, I cannot see any other places in managed code where I can add trace statements to drill down further.

Any suggestions on troubleshooting?

I would try eliminating (commenting out) various items from your XAML until the problem is greatly reduced or eliminated. Likely candidates are databound fields, listboxes, pivot controls with too many items, pivots within panoramas, Converters, etc.

Once you find the source of the slowdown you can begin to work on the cause.
