DataGrid is quite slow, takes ~1s to display 3 tables with 20 rows and 8 Columns

[Trolldemorted]

Describe the bug

A simple demo app with a page that has 3 DataGrids with 20 rows and 8 columns takes ~1s to display, with 600ms going into layouting. It might be that I am doing something completely wrong, but I couldn't find a way to bring things up to speeds where users wouldn't notice the blocked UI thread.

Are 160 elements too many for DataGrid?
