[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-3357) session.clear() takes too long

session.clear() takes too long ------------------------------ Key: HHH-3357 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3357 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.5, 3.2.6 Reporter: Jay Erb Attachments: LazyInitializerPatch.txt Clearing a session that contains a large number of Proxies takes a very long time. The reason for this is that null is set on the LazyInitializer when clearing the StatefulPersistenceContext, whenever a new session is set on an AbstractLazyInitializer, a check is done to see if the AbstractLazyInitializer is still attached to its previous session (and correctly throws an exception if it is). This check performs a linear search through all Proxies in the PersistenceContext. Since we're setting the session to null, do we really need to do this expensive linear search? I propose we not perform the linear search if the session being set on the AbstractLazyInitializer is null.
