[rules-users] How to improve performance with large number of rules and facts ?

Hi alll, In my project i'm loading 18,000 rules ( 3mb file ) to reason with 11,000 facts. I recorded following time durations. - Rule loading time - 3 min 6 seconds - Time duration to create stateful knowledge session - 5 min 52 seconds - Fact inserting time - 5 min 31 seonds - Time duration to fire all rules - 8 seconds I want to reduce these times. I'm new to drools and using standard drools rule evaluation codes ( using insert in a loop to insert facts, creating knowledge session and call fireAllRules() ). Is there a way ( ex: batch operation etc ) to improve performance in any area specified above ? Any direction will be helpful. ( In my project requirement does not allows to use stateless session ) Thanks ! -- View this message in context: http://drools.46999.n3.nabble.com/How-to-improve-performance-with-large-n...
