WPF DataGrid is extremly slow, how can I improve the Initial Loading time ?

Question

Hello,

I have a Window with a DataGrid showing grouped Data.

I am loading around 4 x 300 items in the WPF DataGrid which are grouped in 4 groups.

Grouping disables Virtualization.

I set IsAsync="True" so my Window opens fast but the DataGrid is just filled AFTER 11 SECONDS ???

What can I do to speed up the loading/display of my data?

You stated it yourself - grouping disables virtualization; I think for now showing each group separately (in its own datagrid) is the way to go if at all possible... or some other similar trick to simply not show all the items using grouping.
