[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-2323) Insert on an object with oneto many relationship becomes slow in some machines

Insert on an object with oneto many relationship becomes slow in some machines ------------------------------------------------------------------------------ Key: HHH-2323 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2323 Project: Hibernate3 Type: Bug

Components: core Versions: 3.1.1 Environment: using jdk1.4.2 on windows mcahine xp professional., hibernate 3.1.1, SQL server 2005 using jdbc driver from mticrsoft Reporter: Krishnan Natesan

My application picks up messages from a message queue and persists two objects with one to many relationship. The objects are Object A --------< Object B There are about 4000 messages that need to be persisted. The Object A would be instered from the first message and in all subsequent messages the same object would be used. Each message has One Object A and 900 Object Bs. In one machine the persistence is fast about 50 mins while in the other it takes about 5 hrs. While when I did the persistence with jdbc in both machines it was 50 mins To me it looks like in the slower machine hibernate is not doing bacth inserts.
