Przemo Pakulski commented on JCR-1242:
--------------------------------------

With proposed patch serialization/deserializations of node references is about 2 times faster
than before, it is especially important (visible) when you operate on multiple referenceable/versionable
nodes.

> BudleDB PMs use currently Serializer class to serialize, deserialize node references.
Those methods are unefficient, it use string representation of UUID, namespaceURI and localName.

> For UUID rawBytes should be used and for namespaceURI, localName namespaceIndex/nameIndex
should be used to improve efficiency of serialization/deserialization.
