SfListview vertical scrolling very lagging when using Orientation="Horizontal"

[Kien.Phat]

Hi, I have a ContentPage with element tree like this:

<ScrollView>

     <StackLayout>

          <SfListView Orientation="Horizontal"/>

          <SfListView Orientation="Horizontal"/>

          <SfListView Orientation="Horizontal"/>

     </StackLayout>

/<ScrollView>

The problem is when im tap to any item of SfListView and start swiping up or down to scrolling then it's just scrolled a little bit and seem very lagging.

Can i improve the performance of this once?
