------------------------------------

Hello Karuna,
Did you try with JSON payload format. JSON payload is lighter and compact. 
Please check whether you face significant performance issue with JSON format 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 ?
