[rules-users] Speed up inserting of rules into knowledge base

Hello. I'm loading a big amount of rules during starting of JBoss (20000 rules). All rules (in string format) are available before JBoss startup - they are stored into database. Rules are loaded one by one and it takes about 90 minutes. I want to speed up this process. Is there something like "bulk load" for inserting rules into knowledge base or another smart way to fast loading a big amount of rules? I'm using: 1) Drools 5.1 2) JBoss 4.2.3 My source code looks like this: String rule = ... Resource resource = ResourceFactory.newReaderResource(new StringReader(rule)); KnowledgeBuilder knowledgeBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); knowledgeBuilder.add(resource, ResourceType.DRL); knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages()); Regards, Piotr
