I have no actual knowledge of how this particular database is set up, but that doesn't make much sense to me unless the database is poorly designed or certain kinds of redundant checking are involved. Is there, by any chance, a constraint that all PMs have to be unique to prevent accidental double-sending or some such? I could see that making an import take forever by forcing the database to compare each PM to all previous PMs before inserting it. If such a constraint does exist, removing it temporarily for the import should speed things up dramatically.
