   Ideally there would be a persistent R-Tree implementation similar to dboe's BPlusTree.
   
   But even just serializing the in-memory data structure as a whole rather then having to rebuild it on start-up would be an improvement.
   Also, using [kryo](https://github.com/EsotericSoftware/kryo) serialization (is BSD-3 compatible with Apache v2?) would most likely be faster than java serialization.
   I suppose parallel read/write of tree data structures should be rather trivial to implement when going with the in-memory index solution for now.
