Thank you for your reply.

We are not able to show the exact scenario in stackblitz since the data is sensitive however, we managed to run the demo code from your website for the virtual TreeGrid and captured a video of the behavior of the cpu that goes over 50% when scrolling a relatively small table.

Is this the expected behavior?

For the tree that we tested that has over 1,000 nodes in 5 levels of hierarchy, even in the virtual TreeGrid, the cpu went over 100% and caused the page to freeze.

Thank you for your prompt reply. Just to make sure before we continue to do more tests with the virtual tree grid, in case we theoretically expand all the nodes and scroll the expanded tree – will it have the same performance “problem” as the regular TreeGrid?
