Re: [rules-users] Speeding up Drools

HI. I am using declared types in my .drl file. I have a declared type with 1000 fields (using the Drools 5.5. beta, so 1000 fields is allowed). I have 100 rules. However, creating the stateful knowledge base is very slow. It is taking nearly 8 seconds. Can somebody tell me, suggest how can I speed up the process? Briefly, this is how I measured. long loadI = System.currentTimeMillis(); // load up the knowledge base KnowledgeBase kbase = readKnowledgeBase(); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); ksession.setGlobal("cList", new ArrayList<Integer>()); FactType fact = kbase.getFactType("com.sample", "Project");

Object projIns = fact.newInstance(); ksession.insert(projIns); long loadO = System.currentTimeMillis(); System.out.println("time to load facts : " + ((loadO / 1000.0) - (loadI / 1000.0))); ksession.getAgenda().getAgendaGroup("Group Config").setFocus(); ksession.fireAllRules(); ksession.getAgenda().getAgendaGroup("Fact Config").setFocus(); ksession.fireAllRules(); ksession.getAgenda().getAgendaGroup("Group 0").setFocus(); ksession.fireAllRules(); ksession.getAgenda().getAgendaGroup("Group 1").setFocus(); ksession.fireAllRules(); ksession.getAgenda().getAgendaGroup("Group 2").setFocus(); ksession.fireAllRules(); Many thanks Phani -- View this message in context: http://drools.46999.n3.nabble.com/Speeding-up-Drools-tp4020132.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
