[Neo] Fwd: Performance question

[Atle Prange]

I got the same thing:

Here is my answer to your post:


        I agree with you completely, and i am trying to get the best of
        both worlds. Maybe bytecode manipulation is the only way to
        go.... 
        
        But are you in fact saying that i am implementing an
        antipattern, and both jo4neo and neo-persistence use the same
        antipattern? 
        
        
        
        
        
        
        
        A related question on performance. When fetching relations from
        a node using Node.getRelatioships(RelationshipType...types), is
        the node loading all relationships, and the collecting all of
        the given types, or are just the matching relationships loaded?
