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.
