[rules-users] Performance issue

[Ini]

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?

Thanks,
Ini
