i heard someone said jbpm has performance issure, i am worried about this very much. mainly because of taskinstance table, which does not have history table and will become very large if system runs in a long time. As many constrain in table, its very diffucult to delete data of taskinstance. Someone has good way to solve this problem, or increase the perfomance?
