Hi,
 
Well, first of all you are asking jBPM 3 question. As to my knowledge jBPM 3 
has been transformed into Activiti and moved out. jBPM 5 is a completely new 
product and is rooting from the Drools.  I can be wrong on this, so forgive me 
if I am. 
Secondly, your question mostly relates to how Hibernate works/performs. Our 
company currently working with jBPM 5.2 and we had problems with some SQLs 
containing in orm.xml files coming with jBPM. The SQL’s are less then optimal 
and Firebird DB is dying executing them. But it is not jBPM but Hibernate (and 
perhaps Firebird). Our approach was to not using “bad” SQLs but write our own 
optimized SQLs and execute them via Hibernate’s Native Query mechanisms. 
As to jBPM 5 performance - we do not have any complains so far.
 
Hope this helps.
 
Thanks,
 
Vladimir
