Hi,

I added  30,000 items to the scene.
While updating the scene, the response from the view is very slow.

Among these 30,000 items only 3,000 items have the distinctive locations
and the rest of 27,000 items have the same location of those 3,000 items.

In such a scenario to improve the performance, what flags
I should use on the scene to improve the performance.
