There is no maximum - it's what ever your memory and CPU can take. But largest we'd seen so far in real life was 250K for a medical system.

Tbh if you are loading 600K rules in about 45seconds, that seems pretty reasonable to me. Some other commercial systems would not scale to that :)

Actually thinking about this, we should be asking you to do a public testimony - "Drools scales to 600K rules for a real production system", let me know if you can :)

If you do start profiling (which would be nice if you could) you can ask Qs about Drools internals here. Or on irc:
http://www.jboss.org/drools/irc

But further Qs on partitioning, or general "how to" or "What's recommended" Qs, should be continued on the USER list.
