For which tasks in particular are you seeing this king of gain?
so called "imports".
we get data from external source, check it's id number, fetch the same object from database (if it exists), compare, update changes. if it didn't exist earlier - insert.
such a procedure "touched" directly 7 tables, and about 20 other using triggers and other means of automation.
