BPu00B4s Load performance

Hi

Experts, I´m in the last stage of CRM Project and I need to upload up to 150.000 BP´s from Legacy system via TXT file.

Currently I´m using BAPI´s to do it, but they are taking long time and consuming a lot resorces (dialog workprocess).

What can I do to improve the load performance???

Best ragards, I will reward good points for it!!!!
