Arthur Meyer commented on JCR-1242:
-----------------------------------

Can we update and apply this patch? This patch improves the performance of saving nodes with many incoming references significantly.

The compression ratio of the reference representation could be improved even further if the reference are grouped by name. 
This way, each name is written only once, which makes the representation of references up to 5 times smaller than the current version.

> 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.
