One of the benefits of using ORDA are the performance enhancements from lazy loading. Lazy loading is the feature where only relavant data of an ORDA request is loaded reducing the size of the data. This feature also applies to the cache, so only the necessary data is loaded into the cache while data that is not needed is not.

So not only does using ORDA improve performance in terms of speed it can also reduce the amount of resources needed for the proceedures.
