Hi All, My front end application has transaction timeout of 200 milli Sec and my code is taking upto 1200 ms to load & compile the DRL & store in cache. So I tried to create a package of compiled DRL so that it saves compilation time at run time, but to my surprise the reponse time increated to 3000 milli sec. Please let me know how to reduce the transaction time? *I was using below method to use DRL:-* ruleBase = RuleBaseFactory.newRuleBase( String droolsPath = folder + "/" + <DRL file name>; File f = new File(droolsPath); FileInputStream fInputStream = new FileInputStream(f); Reader source = new InputStreamReader(fInputStream); PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(source); File processFile = new File(folder + "/" + < rules Flow File Name>); FileInputStream processFileInputStream = new FileInputStream(processFile); Reader processFileSource = new InputStreamReader(processFileInputStream); builder.addProcessFromXml(processFileSource); builder.compileAll(); Package[] pkg = builder.getPackages(); ruleBase.addPackages(pkg); WorkingMemory workingMemory = ruleBase.newStatefulSession(); workingMemory.insert(customer); workingMemory.startProcess(this.processName); workingMemory.fireAllRules(); *I am using below code while using package:-* Resource resourceRuleFlow = (Resource) ResourceFactory.newFileResource(<rules Flow File path>); Resource resourcePackage = (Resource) ResourceFactory.newFileResource(<package File path>); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(resourceRuleFlow, ResourceType.DRF); kbuilder.add(resourcePackage, ResourceType.PKG); kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); ksession.insert(customer); ksession.startProcess(this.processName); ksession.fireAllRules(); My understanding is if we are using package which contains compiled rules then it should take less time as compared to DRL file. Please help me how to sort out this issue.. -- View this message in context: http://drools.46999.n3.nabble.com/How-to-reduce-transaction-time-tp402663...

Hi Steve, Thanks for the reply. Can you please tell me how to use the existing knowledge base? Secondly my issue is mainly about the first request to the application..which is getting timed out from second request onward the system is responding quick.

Thanks & Regards, Mittal A -- View this message in context: http://drools.46999.n3.nabble.com/How-to-reduce-transaction-time-tp402663...
