So, it turns out that if I use Oracle Java in Windows instead of OpenJDK on Linux, the performance is pretty different:
- #1 Skilgannon's Cache-hit KDTree [0.0275] - #2 Rednaxela's kd-tree (3rd gen) [0.0290] - #3 Rednaxela's kd-tree (2nd gen) [0.0309] - #4 Voidious' Linear search [0.5553]
The relative performance of things looks much more similar to what you saw, with a smaller difference between my 3rd and 2nd gen tree, with your one performing better.
Between OracleJava/Windows and OpenJDK/Linux, my 3rd gen tree and your cache-hit tree, swap places it seems.

(Also turns out the server JVM is much better suited for the kd-tree test than the client JVM. Edited this post to switch the results to those using the server JVM)
