I have a report in Jaspersoft Studio. I need add fiveteen 15 subdatasets. What will be more efficient (use tables or use subreports)
I have seen considerable difference between execution times with Tables and Subreports.
Reports with Tables execute way faster when compared to subreports.
I dont really know the reason... but it could be because of the report connections being passed in to other resources that makes it slow for subreports.
I thought, various subreports in a master report were more efficient, but NO. I done a test. fifteen subreports in a master compared to one report whit fifteen tables whit diferents datasets. Tables are most efficient really.
Thank you for your answers!
