I notice in SSMS (SQL Server Management Studio 2016), the query results return within a blink of a second (above 10k+ rows). The result table/grid scroll perfectly smooth, and have an extremely low memory footprint (~80MB) on SSMS. This grid/view-like control way out perform either ListView (~200MB, 2-3 seconds) and DataGrid (~600MB, 8-10 seconds). Even if I turn off all visualization or tweak cancententscroll or fix its height to optimize the speed, they still perform far behind the grid in SSMS, still with sluggish scrolling and GUI operation.
What is behind the grid control used in SSMS that make it so smooth?
