Randall:

Do you come from Oracle by any chance?

In Teradata it is much, much, much faster to delete all of the rows (in Teradata mode - single statement transaction = fastest thing that Teradata does) instead of dropping and adding a table (you mentioned DROP and CREATE). In Teradata, deleting all rows is the equivalent of a truncate in Oracle. So, don't drop a table to delete the rows - too slow and takes locks on the data dictionary. Don't do it!!! Always, always, always delete all of the rows.
