It's probably related to your spinner colony.
If you remove a cylindrical piece from a building, you bounding box will
encompass the building AND the complete cylinder. In that case, YES,
you'll get some, possibly large, performance improvement.
Also, if you start with a large cylinder, remove an almost as large one
to get a curved floor, then chop away the sides to only keep the
buildin's floor, manual bounding with a box can greatly help you.
