[rules-users] Is RETE algo optimizes the performance in a stateless session.

Hi All, In a scenario where lets say 10 rule are to be fired (in any order) in a stateless session than will I get the benefits of RETE algorithm (i.e increased performance). i.e Whether the engine will fire all the ten results in a parallel fashion or Whether the engine will file each rule one by one. How RETE algorithm will improve the performance of the engine for rules fired in stateless session ?
