"I studied this source codes and think I should be able to further optimize it. In the end, I got my kbtree.h macro library. As you can see in my hash table benchmark, the modified version beats STL set while using even smaller memory than the original version." I don't see any such benchmarks in the article, which makes any claims not very useful.
