3.6.0.Final, 4.0.0.Alpha1
When obtaining a path for a node, we have to walk up the ancestors and, for each, find the reference for the child within the parent node. Attached is a method call timing table that shows that several methods make this quite a bit more expensive than need be. In particular, a lot of time is spent inside the Matcher.matches(...) method within the NameValueFactory.create(...) method. And, when trying to find a child and its name within the parent, the LazyCachedNode.parentReferenceToSelf(WorkspaceCache) is getting the complete list of all child references via the LazyCachedNode.getChildReferences(...) method call.
Both of these need to be fixed.
