My point was that you should not do it unless you are absolutely sure why you are doing it. :) Usually it is done because that's the only way an inexperienced developer can get their damaged mapping to work. :) Yeah, I know it can be of use.

Consider a long running (single) transaction where hundreds of records are being inserted. It is possible for the session cache to have so many objects in it that the dirty checking of all those objects takes a huge amount of time. Flushing at regular intervals (e.g. every 50 -100 objects) can improve performance dramatically. In general though I agree with you, but you need to keep in mind that what is good for your application is not necessarily good for every application.
