Custom BAPI

I had copied the standard BAPI into a custom BAPI to post GL transactions. The custom BAPI is part of BO. It's taking huge time around 6 Hr's. But I copied the same custom BAPI into another custom BAPI and it is not part of the BO. It's taking only 50 Min to complete the job. Is there any performance impact if we place the BAPI in BO?
