Description
I am currently migrating our existing LOB app that is on the iOS app store from Xamarin Forms to .Net Maui and I am noticing performance issues in the Maui version compared to the Xamarin version. This is most noticeable when testing on older slower devices such as the 2018 6gen iPad we have access to which is a good representation of the devices our customers would be using.
I have created an example repo https://github.com/brentpbc/maui-xam-testing.git that contains a Xamarin solution and a Maui solution, both have essentially the same code. In the test app there is a "CollectionView2 Page" button, in the Maui version after tapping the button there is a delay navigating to the "CollectionView2 Page" which is not present in the Xamarin version and then once the page is displayed the scroll stutters and doesn't match the performance of the Xamarin version. Both versions were built in Release mode when comparing. See below screen recordings for a comparison.
