Universe of an InfoCube on BW HANA

Hi all,

I have a problem with the performance of a report in Web Intelligence BO 4.1, I hope that somebody can help me.

I did a universe with a connection Data Federator, the source of the connection is an InfoCube Optimized on BW HANA. After that I´ve created a report in Web Intelligence, this report have mandatory filters  for year, month and version but despite of that the InfoCube is Optimized on BW HANA the report don´t have a good perfomance. The Infocube have about 1 million records.

Somebody knows if is recommendable to create connections Data Federator on InfoCubes Optimized? or Is it better to use connections BICS for to create reports on InfoCubes Optimized?

Thanks!
