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.
