Heavy popup content in .NET MAUI apps can block the UI thread and cause visible lag. Four key optimization techniques are covered: caching popup content via ContentTemplate to avoid rebuilding the visual tree on each open, lazy initialization to load data only when the user taps a product, using a virtualized list (Syncfusion SfListView) for large datasets like 1,000 items, and tuning animations with a short duration (180ms) and easing curve to prevent jank. A lifecycle strategy for managing cached popup state is also provided, along with a GitHub sample demonstrating all techniques across Android, iOS, Windows, and macOS.
