The Paginator will further limit the QuerySet before doing anything that causes the QuerySet to be evaluated (causing a read from the database). The Paginator may call count() on the QuerySet to read the total number of items from the DB (I'd have to look at the implementaiton, and it could depend on how you use it), but the actual reading of the data from the table won't happen until your code calls the paginator to retrieve the data in a page.
