When I used Hibernate 1.2.5 to load a few thousand objects into a cold cache by calling Session.find("FROM entity IN CLASS X"), it took a few seconds to execute.  But it took about 7 minutes after I switched to Hibernate 2.0.  It takes about 2 seconds to execute the same test (loading the same entities) if there are no <jcs-cache> elements in the Hibernate mapping files.  Hibernate 2.0 performs much better using the version of lib/jcs.jar that was released with Hibernate 1.2.5, instead of the lib/jcs.jar that was released with Hibernate 2.0.  This combination of software can load entries into a cold cache approximately as fast as Hibernate 1.2.5.

I'm willing to test a better version of JCS, but I have been unable to build it.

P.S. I also filed JIRA report HB-156, but it seems JIRA has lost my report and also my identity (I just enrolled myself again, with the same username).

We need to verify this and find out why....
