To be honest, I don't know. My guess is it would be a bit faster as the consequence would be compiled only once, but I have no numbers to compare... question: are you using a single builder and adding multiple files/rules to it, or are you using one builder per file? Is your application spending most of the time on the builder or adding rules to the kbase? I see you are still using the old API (method addPackageFromDRL())... does the new API make any difference? Also, I know Tihomir was improving perf in trunk by caching the configuration file... did you tried trunk? Does it make difference for you?

For a large rulebase (200k+ rules) will the call to addPackageFromDrl(drlString) run faster if the number of rules is smaller but the rules include more || statements between predicates?

There is only one type of object ever inserted in working memory and I have many rules with the same RHS. I can collapse those rules into one LHS with ors between the predicates in the object, but I would only go through the effort of optimizing if it would improve load time.

Thanks for your help.

Joe
