Yes it helps in improving the performance of the import job because the creation of indexes during the import will be fast as the indexes are usually in a sorted order and the sorting happens in pga. so that essentially means the larger the pga_aggregate_target the fewer the disk sorts during index creation and faster the import.

hope that helps
