NHibernate - ISession vs. IStatelessSession

What is the pros and cons using IStatel开发者_如何学CessSession over ISession in NHibernate?

---

StatelessSession doesn't tracks changes made to the entities and has no lazy loading support. Thats why it has a better performance than Session.

But with stateless session you are forced to manage Insert, Delete, Update operations manually and this really uncomfortable.

Stateless session is made for batch operations where you need to make a lots of queries to database and you don't need tracking changes, etc.
