[Hibernate] slow performance on flush

[Christoph Sturm]

Hi all! I'm trying to increase the performance of this pseudocode:   for (j=1;j<100;j++) {     for (i=1;i<100;i++)     {         session.save(class)     }     session.flush();     session.connection().commit(); }     Now my problem is that flush doesnt take a constant time, but every invocation of flush takes more time than the last one, the more I flush the slower it gets. To me it looks like hibernate keeps the references to the flushed objects in the entries map, and doesnt remove them. Is there anything I can do about it?   regards  chris
