[rules-dev] Final take on performance .

Hi , I have been given an assignment to show case the situation where the performance of a rule engine will be better than java code . My first question is ; Is this possible ? What I had done earlier was I sent an arraylist and I used the 'from' clause , like Mark pointed out for the 'from' statement pure iteration happens and the index is not created . So what I have done now is create a scenario where I insert about 20,000 objects and have 20 rules (each rule has 2 alpha nodes ) . I do the same with java code (if-elses) and the java code wins this competition hands down . Is there a breakthrough point where the rule engine performs as well as the java code or even better ? Appreciate it Harsh ______________________________________________________________________
