Yes, it's the reason. 600K per record... > But since I donesn't include any of the blob fields in the SELECT statement > I can't see no reason why MySQL should scan all the fields. Because MyISAM always reads the record as a whole, it cannot read only selected fields. You can convert your table to InnoDB table type - as InnoDB *can* read only selected fields. Actually, it's useful optimization to store big, rarely selected fields in the separate table. This will also help to speed things up.
