DynamicDataStore.InternalLoad copies dictionary every time

Description

protected internal virtual object InternalLoad(Identity id, Type type, LoadAsObjectType loadAs, ProviderCallContext parentContext)
        {           
            //First check if object is already loaded in the context of this store instance
            object obj;
            if (_identitiesToObjectsMap.TryGetValue(id, out obj))
            {
                return GetObjectInRequiredFormat(loadAs, obj, type);
            }
 
            //Check if object is present in "shared" cache
            ObjectContext cachedObject = CacheProvider.Instance.GetInternal(id.ExternalId.ToString(), type, 
                new LoadingContext() {* CurrentObjects = new Dictionary<Identity, object>(_identitiesToObjectsMap)});*

If the collection is big enough, every time an item is loaded, DDS will create a copy of the dictionary. This is not only slow and wasteful, but also can cause frequent Gen 2 GC

Note for QA: This could be verified that Form postings and reading of form postings work as expected
