I'm no expert in B+ trees, but I understand that these structures are
more effective than regular binary trees when secondary storage (i.e.
hard disk) is used, which is not the case for an in-memory container
like multi_index_container. Have you any reference on the performance
of B+ trees in in-memory scenarios?
