    Hello,

    Welcome to our Microsoft Q&A platform!

    From above code you posted, I found the xaml code is a bit complicated，which has so many controls and layouts. This will effect the loading efficiency.

    For this, you can follow document Improve Xamarin.Forms App Performance to optimize your code.

    In addition, you can also try nuget Xamarin.FFImageLoading.Forms to load your image,which is a Xamarin Library to load images quickly and easily on Xamarin.Forms.

    For more details, you can check: https://github.com/luberda-molinet/FFImageLoading .

    And there is a sample included in above link, you can refer to it.

    Best Regards,

    Jessie Zhang
