For query performance, it's utterly important to create a sound query plan so that as little resources as possible are wasted. The NativeStore currently evaluates joins between statement patterns in the order in which they are supplied by the user/query parser. Most often, this is not the most ideal order. Ordering the statement patterns by their (expected) number of results potentially yields huge performance improvements. A similar approach has sped up query evaluation in the MemoryStore in a previous release.
