Performace Loss Numbers

[blazer]

i know i'm a bit late to the thread just doing some catchup reading. Not sure if the discussion is still relevant.

Is it possible to scan the rule file first and only tell the rule processor to process those rules and not the unnecessary ones, so you won't lose performance for users who aren't using all the rules.

So I guess either have multiple rule engines and pick the best or have a dynamically initiated rule engine if possible.
