Distance display condition performance?

I have a scene where I load in around 10,000 entities via czml with 3d models attached to each. I have it so when you are at a specific zoom level, the models will disappear. However, even when zoomed out, when the models should not be visible, the performance is still the same just as if the models are there. So my question is, how should I optimize this so that this scene will run better? Here is the sandcastle link: t.ly/c_9C


Hi @tealminivan, Datasource clustering should be good option to load entities according to zoom level without hurting performance. There is a proper example related to it’s use.
