Generating self links, especially for lists, is inefficient. Replace use of net.URL.String() with direct encoding that reduces number of allocations. Switch from calling meta.ExtractList|SetList to a function that iterates over each object in the list. In steady state for nodes performing frequently small get/list operations, and for larger LISTs significantly reduces CPU and allocations.
