Drools - 更快地創建KnowlegeBuilder？

我有一個用例，我需要爲一次性使用動態地創建一個規則。規則是動態的，在更糟糕的情況下，每個迭代/請求可能會有所不同。因此，我無法儲存它們。Drools - 更快地創建KnowlegeBuilder？

我目前對Drools的理解是，您需要創建一個KnowledgeBuilder，然後添加規則。

我按如下方式創建知識庫。

private KnowledgeBase readKnowledgeBase() throws Exception { 
long t1 = System.currentTimeMillis(); 
    KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); 
long t11 = System.currentTimeMillis(); 


    kbuilder.add(org.drools.io.ResourceFactory.newByteArrayResource(getRule()), ResourceType.DRL); 

long t2 = System.currentTimeMillis(); 

    KnowledgeBuilderErrors errors = kbuilder.getErrors(); 
    if (errors.size() > 0) { 
     for (KnowledgeBuilderError error: errors) { 
      System.err.println(error); 
     } 
     throw new IllegalArgumentException("Could not parse knowledge."); 
    } 
long t3 = System.currentTimeMillis(); 

    KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); 
long t4 = System.currentTimeMillis(); 

    kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); 
long t5 = System.currentTimeMillis(); 


    Collection<KnowledgePackage> kpackages = kbase.getKnowledgePackages(); 
      for (KnowledgePackage knowledgePackage : kpackages) { 
        System.out.println("Package -------- " + knowledgePackage.getName()); 
        Collection<Rule> rules = knowledgePackage.getRules(); 
        for (Rule rule : rules) { 
          System.out.println("****" + rule.getName()); 
        } 
      } 
long t6 = System.currentTimeMillis(); 

System.out.println((t11-t1) + " " + (t2-t11) + " " + (t3-t2) + " " + (t4-t3) + " " + (t5-t4) + " " + (t6-t5)+ " "); 

    return kbase; 
}

基於定時登錄只有這兩個操作的時間的代碼取大多數（超過80％）。有沒有辦法讓它更快？或者有沒有辦法實現我的用例？

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); 
kbuilder.add(org.drools.io.ResourceFactory.newByteArrayResource(getRule()), ResourceType.DRL);
