We also see SharedSingletonMap accounting for 3.4M (15%) objects holding 79MiB (12%) memory.</p> <p>Once we have <a href="https://jira.opendaylight.org/browse/YANGTOOLS-1020" title="Add runtime-generated Immutable maps" class="issue-link" data-issue-key="YANGTOOLS-1020">YANGTOOLS-1020</a>, we should be able to generalize that solution to generate NormalizedNode implementations, which do not reference, but rather embed the child map.</p> <p>That would lead to elimination of {SharedSingleton,ImmutableOffset}Maps, or really any internal data structure, shifting those overheads to the generated class, where they are amortized among all instances without additional cost.</p> YANGTOOLS-1021
