>          Key: NH-1001
>          URL: http://jira.nhibernate.org/browse/NH-1001
>      Project: NHibernate
>         Type: Bug
>   Components: Core
>     Versions: 1.2.0.GA
>     Reporter: Tomer Avissar
>     Priority: Minor

>
> When using the not-found=ignore attribute in a one-to-many/many-to-many, NHibernate is issuing a query for every element not found in the collection, even when using an outer join. 
> In some cases this causes a significant performance overhead.
