    I bind JumpList to List with 500 elements. Item template is a bit complex(contains Image, Path).
    Page with this JumpList loads very long time.

    Should i use some manual virtualization technique ?

    Thanks for writing.

    You can try setting the RealizedItemsBufferScale to reduce the length of the UI Virtualization buffers. By default, the value of this property is equal to 2, which means that each UI virtualization buffer (upper and lower) will be twice the size of the viewport. You can set it to 1.5 for instance, to make the ratio smaller and thus prevent RadJumpList from realizing more containers at once.

    You can also try setting the IsAsyncBalance property to true to speed up startup performance.

    I hope this helps.

    edit: Nevermind, RadJumpList is plenty fast but my forgotten Debug.WriteLine slowed it down.
