Data binding loadAll() method and client updates

I have a rather simple question for the ZK gurus. As known i can use the AnnotateDataBinder.loadAll() method to update the components with fresh data from the model. I understand that this enforces the server to send the required updates to the client DOM.
Does anybody knows if the ZK makes any optimization to avoid sending changes for those components that model data was not changed? If not then it would be more efficient to use AnnotateDataBinder.loadComponent() to update components selectively?
The above is question is applicable also for the other way around, saveAll() vs saveComponent().
