2565	Documentation should clarify lazy nature of querysets	Simon Willison	Jacob	"I've answered a couple of comments in the documentation recently about QuerySet lazy evaluation:

http://www.djangoproject.com/documentation/tutorial4/#c2024
http://www.djangoproject.com/documentation/models/pagination/#c2032

That's enough for me to think that this is a frequent misunderstanding. We certainly don't want people to be put off Django because they think it makes horribly inefficient queries, when the exact opposite is true!

An entry in the FAQ would be a good start, but having notes (and a link) about this behaviour in the relevant places in the docs would be smart too."	enhancement	closed	Documentation		normal	fixed			Ready for checkin	0	0	0	0	0	0
