[rules-users] Doubt regardging Drools-RETE

Hello everyone, 1. If there are not many common facts i.e all rules are operating on distinct facts / data. Does this mean the algorithm will not bring in much benefit ? 2. Also if the facts are same but the LHS of a rule is quite different from others then will RETE have its benefits. I have gone through the RETE algorithm documentation and RETE node diagram chart but still finding difficulty to understand it. Can somebody please provide a layman language link to understand RETE.
