get number of childs test
getting node took 6 milliseconds
node have 100 childs 
(System.out.println( "node have " + node.getNodes().getSize() + " childs ");)
getting node child number took 2 milliseconds

get uuid test
getting node took 7 milliseconds
node have uuid 1042b872-4e1f-4600-b87d-505bbd13f71f
(System.out.println( "node have uuid " + node.getUUID());
getting uuid took 0 milliseconds

well I'm not there is direct way to do that
