Re: [rules-dev] Which of these scenarios will lead to better performance?

Hi, Consider that I have 500 instances of interface userI. Now, there are 3000 rules currently written based on a combination of these instances. if { $a : userI (name = "A") $b : userI (name = "B") } then { //do some actions } How many tests are needed for a match in the RETE network for this rule? If I created 500 classes, one for each object, such as UserA implements userI and so on... my rule will look like: if { $a : UserA() $b : UserB() } then { //do some actions } Will this lead to better performance since there will only be one such instance of this object? As for class-loading concerns, will there be a parsing/memory penalty to be paid for having 500 classes now instead of one?
