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?

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

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.
