Re: [rules-users] Performance issue

Hi Laune, As you suggested i divided the validate method into three as below: public static void validate(Object beanDetails,String rule, List errorsList){ long methodStartTime=System.currentTimeMillis(); KnowledgeBase kbase =createKnowledgeBase(rule); StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession(); ksession.setGlobal("errors", errorsList); ksession.execute(beanDetails); long methodEndTime=System.currentTimeMillis(); System.out.println("Time taken in Method validate in milli seconds is::"+(methodEndTime-methodStartTime)); } private static KnowledgeBase createKnowledgeBase(String rule){ long methodStartTime=System.currentTimeMillis(); KnowledgeBuilder kbuilder = createKnowledgeBuilder(rule); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() ); long methodEndTime=System.currentTimeMillis(); System.out.println("Time taken to build KnowledgeBase::"+(methodEndTime-methodStartTime)); return kbase; } private static KnowledgeBuilder createKnowledgeBuilder(String rule){ long methodStartTime=System.currentTimeMillis(); KnowledgeBuilder kbuilder =KnowledgeBuilderFactory.newKnowledgeBuilder(); Resource resource = new ClassPathResource(RULE_CLASSPATH+rule); kbuilder.add(resource, ResourceType.DRL ); KnowledgeBuilderErrors errors = kbuilder.getErrors(); if (errors.size() > 0) { for (KnowledgeBuilderError error: errors) { System.err.println(error); } } long methodEndTime=System.currentTimeMillis(); System.out.println("Time taken to build KnowledgeBuilder::"+(methodEndTime-methodStartTime)); return kbuilder; } but i am not able to understand , how will this help to improve the perfoemance?
