<html><body bgcolor="#FFFFFF"><div>Thanks for the reply. But I don't understand what you mean by caching the KnowledgeBase. This is about adding a pre compiled KnowledgePackage to a KnowledgeBase. So, how does caching a KnowledgeBase makes addition of new KnowledgePackage faster? Please excuse my ignorance if I am not catching what you are suggesting. Maybe a couple of lines of code to demonstrate your suggestion would be greatly appreciated. Thanks. <br><br>Sent from my iPhone</div><div><br>On May 3, 2010, at 1:24 AM, Rajnikant Gupta <<a href="mailto:capricorn.raj@gmail.com">capricorn.raj@gmail.com</a>> wrote:<br><br></div><div></div><blockquote type="cite"><div><div>Hi,</div>

<div>Yes, adding packages to knowledgeBase does take some time. You can probably try caching your knowledgeBase. By doing this all, but first, requests should be significantly fast.</div>

just to execute the following statement:<br><br>this.knowledgeBase.addKnowledgePackages(packages);<br><br>where "packages" is just a list of one knowledge package representing one<br>drl. The nature of my rules is that I initially load a small set of rules<br>
and then at runtime my rules may load other DRLs. The problem is each DRL<br>loading command (this.knowledgeBase.addKnowledgePackages(packages)) takes a<br>few seconds and I have no idea why. Although, all those DRLs are already<br>
compiled (at startup time). It is the line I pasted above that takes the<br>longest time out of anything else I do.<br><br>Any idea why just merely adding a KnowledgePackage list to a KnowledgeBase<br>can take this much time? Do you guys have any suggestions on how I can<br>
reduce this time? I tried to create another dummy KnowledgeBase and get the<br>KnowledgePackage from it at runtime and add that to my KnowedgeBase above<br>(thinking that would reduce the time maybe), but not at all.<br><br>
Any ideas would be great. The API does not have much info on what that add<br>method exactly does behind the scenes, and how I can get around the long<br>delays. This is very frustrating to me, and I am not sure where to look.<br>
Thanks for ANY help at all.<br><font color="#888888">--<br>View this message in context: <a href="http://drools-java-rules-engine.46999.n3.nabble.com/addKnowledgePackages-Delay-tp772574p772574.html" target="_blank"><a href="http://drools-java-rules-engine.46999.n3.nabble.com/addKnowledgePackages-Delay-tp772574p772574.html">http://drools-java-rules-engine.46999.n3.nabble.com/addKnowledgePackages-Delay-tp772574p772574.html</a></a><br>
