In the old and new implementation there are two different algorithms
implemented so I guess the exact comparision of the building process
isn't possible. I was surprised that query takes more time because it's
basically one loop with comaprision of bounding boxes and function call.
I performed more tests and figured out that there is an bug which causes
incorrect tree to be created. I'm currently looking into the matter.
