Drools - 更快地创建KnowlegeBuilder？

我有一个用例，我需要为一次性使用动态地创建一个规则。规则是动态的，在更糟糕的情况下，每个迭代/请求可能会有所不同。因此，我无法储存它们。Drools - 更快地创建KnowlegeBuilder？

我目前对Drools的理解是，您需要创建一个KnowledgeBuilder，然后添加规则。

我按如下方式创建知识库。

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; 
}

基于定时登录只有这两个操作的时间的代码取大多数（超过80％）。有没有办法让它更快？或者有没有办法实现我的用例？

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