After changing to pessimistic locking, our test results have dramatically improved. It turns out to be a known issue in 1.2.4 SP1.

In case anyone stumbles upon this issue, below is a very useful link referring to the phenomenon.

http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheOptimisticLockingPerformance

Also referred to from:
http://wiki.jboss.org/wiki/Wiki.jsp?page=OptimisticNodeLocking

It would be nice to be able to reach (one of) the above pages from a page titled "Performance we should expect from PojoCache"
(http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheOptimisticLockingPerformance),
but that's my opinion.
Maybe the results would have been expected - 170 (!) times faster.


Thanks for all the help,
