To evaluate the speed of data grids rendering grouped data. I use the exact same data consisting of 500 rows of weatherforecasts, and then create a grouped grid for each Blazor component suite I can find.
- Initial time to data rendered
- Render performance when scrolling
- Initial time to group by a column
- Time to expand a group with a single row inside, when all other groups are already expanded
