>
> XXPolicyRef objects have fields such as create time, update time, added by
> user ID, updated by user ID, but there fields are entirely useless since they
> are all copied from the XXPolicy object. In addition, while improving
> performance for creation of policies with large numbers of users, we
> discovered that a lot of time was being spent in JPA converting these Date
> objects especially. After removing these fields we saw a significant
> performance improvement (a secondary benefit is less database space usage).
