yeah...i saw that a while ago...very interesting. BUT the most important thing is the resources it take from the system (ie memory) to load 5000 (rough estimate on our rule count) rules with drools 2.x and with drools 3.x
i think i will do a branch on my clearcase project and will start working on this. question..my xml rules are separated in entities, how i do that with DRLs? Joel G.

I think someone worked on a XSL to transform 2.x XML files into 3.x ones, BUT if you do that, you don't get most of the performance benefits of the new version. The reason is that there is no automatic way to convert old <java:condition> elements into field constraints... only in evals(). It requires investments, and it is not always easy/viable for companies, but the best solution is indeed to convert the XML rules into the new DRL language. Have you seen that? http://markproctor.blogspot.com/2006/11/rush-hour-and-content-based-routing.html It is a customer case with a performance benchmark between drools 2.5 and 3.0 (3.2 is even faster). It may help to justify such investment... []s Edson Joel G.
