http://woolfel.blogspot.com/2006/03/jess6-vs-drools3-vs-clips-623.html Since last Spring, Drools has been making steady progress on improving the core RETE implementation. Tonight I ran manners64 in both Jess6 and Drools3. Jess 6 - 2208 ms Drools 3 - 9781 ms CLIPS 6.23 - 67.219 seconds To put things in perspective, JESS is one of the fastest RETE engines and many commercial engines can't beat it. Take for example Blaze Advisor, which has been around for over a decade. The old blaze engine was slow. It's well known within the rule industry. Last year FairIssacs bought RulesPower, to get a faster engine. In the last 8 months, Mark has rewritten Drools core and managed to make significant performance and scalability improvements. Using the old Drools2 core, 16 guests took several minute. Now 64 guests finishes within 10 seconds. A modest guess is that drools3 is atleast 10-20x faster than drools2. Hopefully the users will appreciate all the hard work the drools team put into drools3. It's nice to know the code I contributed last year has helped Drools 3 match CLIPS 6.23 performance.
