    both Xamarin listview and Telerik's Radlistview, for some reason, has expensive binding and initialization. this cause to performance penalty.

    luckily, there is a solution for that, called fastcell.

    I have tested the library, and indeed performance are much better, especially on old devices.

    however, I couldn't find a way to integrate the fastcell with the telerik's listview.

    also there isn't a custom renderer for cell, so its not possible to override it.

    any suggestions?

    there is no need to actually use that, because Telerik Listview is quite optimized well. (In my case, I ended with building cell content with absolute layout and it did solve the performance issues)

    however, this is the answer I got:

    You can see that the OnCreateViewHolder() method is of type ListViewHolder. 
    So you should return an object of that type. 
    Such objects are created based on a XamarinForms Cell. 
    That is why you will need to first create a Cell. 
    Next you can use CellFactory.GetCell() method in order to get the XamarinForms View that is used in the cell. 
    Using that View you will be able to create the needed ListViewHolder object.
