I have a very similar issue - so I'm interested in any further performance
tips or findings:
We use Drools with an interface where users can update / edit rules. Those
rules are then stored (and versioned) in a database. Afterwards the rules
are fetched again from database and added one by one in
Hello.
Some time ago I wrote an e-mail with question how to parse and load a
large group of rules in an efficient way. I've made a lot of tests and I
have couple conclusions. Is there a possibility that someone could
confirm (if I'm right) or deny (if I'm wrong) my conclusions, and

you may reconsider the structure of the rules.
Push instead of pull. This means compare the file time or content to the
database and only recreate rules that have modified. This way you can
update the serialized packages where appropriate.
Without knowing what your rules looks like I can
