My experience has been that for many tables, it is much faster to drop the indexes, do the import, then rebuild the indexes; otherwise, the import can take an inordinate amount of time (at least as much, because it is stuffing data into a table with an index(es), so it rebuilds it on the fly (less efficiently, I would guess)).
