> DocumentNodeState objects and other related data is currently identified with
> a String path in the various caches in the DocumentNodeStore. Read benchmarks
> like GetDeepNodeTest that only read data from memory are significantly slower
> on a DocumentNodeStore compared to a SegmentNodeStore. In these kind of tests
> the DocumentNodeStore is usually busy with String operations like
> constructing the path for a child node or calculating the hash code for a
> lookup in a cache.
> This issue is about a potential improvement that replaces the use of a plain
> String for the path of a DocumentNodeState and use a custom Path type instead.
