[rules-users] Functionality/Performance Test Results

Our users are asking to be able to specify custom validations in our application. I've been undecided whether to use a rules engine or write our own dynamic validation code. While it's admittedly still in the "toy problem" stage, I tried using drools in place of some existing hand-coded validation. The drools version took the SAME amount of time. Then I added another rule, to simulate the types of validations our users want to add, and re-ran. Again, SAME time. Admittedly, database access was the big time consumer -- average of 6 seconds per unit of work, and about 15 units of work per test -- but it was the same for both the rules-based and hand-coded validations. Excellent work, everyone! You've made my life much, much simpler!
