Hi Team, I think your help will be really helpfull for my situation, We are having 30k rules and we have converted those set of rules in to pkg files. 1. knowledgebase loading time takes upto 40 - 60 secs . Is this time ok ? 2. when we try to load 20 set of these 30k rules we are facing problems -

Any help would be helpfull . Note : Java heap space 2gb and permgen space is 512mb Thanks in Advance, M.Sundar -- View this message in context: [http://drools.46999.n3.nabble.com/Reg-Handling-large-number-of-rules-tp40...] http://drools.46999.n3.nabble.com/Reg-Handling-large-number-of-rules-tp40...

Thanks Laune for you reply , I meant 20 set as we need to have 20 x 30k rules to be loading in knowledgebase in our application.

So you are loading 600K rules into one rule base, 30K rules at a time??

On the current release, there isn't much you can do. But you could try using a profiler against 6.x, and look out for any bottlenecks. The rete builder code is fairly simple, so I'm not sure how much room for optimisation there is; but you never know what you might turn up. Probably the main gains would be from parallel rule addition, but that is a lot of work, and planned for the future - so won't help now. Always a good task for someone with some time :) You may be able to change your application to be more data driven, rather than encoding it all in the rules - this might help reduce the number of rules. Btw we are always looking for real world test cases, so maybe could submit your 600K rules as one?
