In the Session.flush method has a lost of perfomance about 50% when flush a large amout of data ----------------------------------------------------------------------------------------------- Key: HHH-5062 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5062 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.5.0-Final, 3.5.0-CR-2, 3.5.0-CR-1, 3.5.0-Beta-4, 3.5.0-Beta-3, 3.5.0-Beta-2, 3.5.0.Beta-1, 3.3.2, 3.3.1, 3.3.0.SP1, 3.3.0.GA, 3.3.0.CR2, 3.3.0.CR1, 3.2.7, 3.2.6 Environment: Linux / DB2 / version 3.2.6 and above Reporter: Fabiano Cury Attachments: issueHibernate.JPG When the flush method is called this method call the onFlush method of class DefaultFlushEventListener and then the method flushEverythingToExecutions(event). This method (flushEverythingToExecutions) call many times (loop) the method log.isDebugEnabled(). This cause a big overhead in this method. I suggest you to put an attribute in the method flushEverythingToExecutions(flushEverythingToExecutions(FlushEvent event, Boolean isDebugEnable) and verify this attribute before the loop for. Attached the print screen of profiling that help me to detect this issue.
