What's the insert performance like for the WPF Toolkit DataGrid?

Question

Hi all. Just wondering if anyone knows about what performance is like for the WPF Toolkit DataGrid for inserting rows to the top of the visible area. I know that ListBox and ListView will recreate all new visuals for all of the rows that are pushed down, which is a major impact on performance; I was wondering if the WPF Toolkit DataGrid does the same thing.

WPF Toolkit DataGrid should do 'Virtualization', which is what in Microsoft speak is 'reusing WPF objects' (see for example http://www.ytechie.com/2008/09/disabling-wpf-datagrid-virtualization.html).
