[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3991) Bad performance when clearing big sessions

Bad performance when clearing big sessions ------------------------------------------ Key: HHH-3991 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3991 Project: Hibernate Core Issue Type: Bug Components: core Reporter: Thomas Jacob If a session has many proxies, clearing is very slow. The reason is the AbstractLazyInitializer.setSession checks if the proxy is already connected to another session, which in turn linearily iterates through a referenced map. Since the method receives a null (clearing unsets the session), this check is not necessary. I suggest setSession's line 2 to be changed from if ( isConnectedToSession() ) { to if ( s!= null && isConnectedToSession() ) { In addition, the linear iterations should be replaced, as a performance improvement. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
