[rules-users] Usage of Drools Configuration Attributes

This email thread prompts me to ask a more general question - is there a performance or tuning guide for any of Expert, Fusion, jBPM, etc that describes what configurations/tuning options there might be for any of the various Drools components, how one can go about modifying those, and some sort of sizing guidelines one could use to make such modifications?
