[rules-users] Re: Performance Tuning

I assume you are on 3.0, as the properties system should be overhauled. However left beta node indexings should be true, for both 3.0 and 4.0. I can't remember if alpha node hashing is true or false in 3.0, but in 4.0 its false as default and then gets turned on when you try to do dynamic rule additions. But in all honest you shouldn't be touching that stuff unless you really know what you are doing. Turning of left beta node indexing only improves performance for rules that are always activated from the root (first) pattern.
