Data Loading - Performance Improvement ( Calculation View to DSO in BW4HANA )

Hi Team

We have created a calculation view in SAP HANADB and then via ODP created a datasource on top of it & then loading data to DSO.

But we see some performance issues while loading the data from CV to DSO.

The Filling Transfer Intermediate Storage and Data Package 1 taking 1Hr + time. Could you please help in suggesting some points to improve performance ?

Best Regards,
