The default R-Tree code uses the "R*-tree algorithm" for splitting. While this should typically perform better than the other two variants (Guttman Quadratic and Linear splitting), you may want to test them with your data set and queries to see if either performs better. You will need to compile and change the #defines at the top of rtree.c to test these variants.
