     The depth directly affects performance and memory usage; the latter
     growing exponentially with the depth of the tree. With an optimal tree
     depth, the index can instantly determine the locality of items, even
     for scenes with thousands or millions of items. This also greatly improves
     rendering performance.

     slowdowns as the index retunes the depth internally. You can avoid
