oh wow.. yes,
try this for starters (pseudocode):
new_rows = new List(500)
i = 0
for row in file:
new_row = RowType( somedata)
if (i < 500)
new_rows.add(new_row)
i++
else
i = 0
new_rows.put()
new_rows.clear()
new_rows.add(new_row)
i++
that should decrease the amount of puts you do into the datastore by a
factor of 2
