Folks, just an fyi, we discovered an issue recently with the way in which Isis configures JDO objectstore that might cause performance issues.
There is a one-liner fix, though there are also implications for your code which you should double check. A write-up of the issue and fix is on the website here [1] Thanks Dan [1] http://isis.apache.org/components/objectstores/jdo/disabling-persistence-by-reachability.html
