NHibernate version:
Version 1.2 Beta 1

Hello all!!

I have a problem or a doubt with the beta 1 of version 1.2

I´m using always the same session object

When I do a session.Flush() this function try to flush all the objects even when it's not necessary. Is that normal?

On the other hand, I have session.flushmode = auto. When I do a query because the flushmode is auto Nhibernate flush all the objects, and when I do a new query all the object are flushed again widthout any pending insert, update.... It slow down the app a lot, someone realized this issue?

You are probably discovering 'transparent-write-behind' where NHib synchronizes the Db on each Flush() with any entities that were brought in during that Session.
This is normal behavior. If you really want to control it more granularly you can change tthe flush mode to Commit and it will only synchronize when you tell it to.

Hibernate in Action the book has more details.
