this is fixed or any plan to fix or any work around of this?
We want to apply filter on main entity and expanded entity as well

> We have a very large data base and we are exposing the data using olingo
> restful web service. when I compare, time taken to execute the same query via
> jdbc connection and time taken by olingo, there is a significant difference.
> Time taken by Olingo is very large.
> Time taken to process JPA query + Time taken to build response is the total
> time taken by olingo.
> We try to tune the JPA queries using Query hints, but still build response
> time is also very large.
> I have a question :
> Is there any way we can reduce the time taken to build the response ?
