Need to optimize the performance of Blazor WebAssembly TreeView

While trying to load large number of data let say 2000 nodes of 100 parent node with 20 child node in Treeview. The time taken to load at initial as 8500ms without any expand action which causes the performance issue in Treeview.

Need to check the time taken for the below items with the large data set and optimize it. Check with and without template rendering.

  1. Expand a parent node with large set of child nodes(10k)
  2. Checkbox selection with 10k child nodes.
  3. Ensure initial rendering time taken for normal node selection using property with the large data set

Expected: Treeview Web assembly application should also works without any performance delay.
