Automatic merge from submit-queue SetSelfLink is inefficient Generating self links, especially for lists, is inefficient. Replace use of net.URL.String() call 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. @wojtek-t this is the next big chunk of CPU use during the large N nodes simulation test (11% of master CPU). Takes a few allocations out of the critical path
