Lumira 2.0 run slowly

Dear All.

I'm recently use Lumira 2.0 to develop report.And the report run slowly,even though I just have one datasource,or I just carry a filter,which will spend several times than SAP BusinessObjects Design Studio.And in design studio,I can add "&PROFILING=X"to analysis time spend.But in lumira 2.0,it haven't design studio convenience,which will show like follow picture.

And my version is:2.0 SP2 (Version: 20.2.0).

Thanks.
