"unserializing the EntityIdValue (e.g. from memcached) from the entity type + numeric id format to an EntityId object has significant impact on performance and memory usage. The unserialization uses the PropertyId::newFromNumber and ItemId::newFromNumber methods are memory intensive, with use of strtr ([[ https://github.com/wmde/WikibaseDataModel/pull/5 | #5 ]] in https://github.com/filbertkm/wb-profiling/blob/master/memory_own-itempurge-1.25wmf1.txt). If we can somehow move away from entity type + numeric id format in EntityIdValue, I think that would be better." https://github.com/wmde/WikibaseDataModel/issues/248
