Re: [rules-users] Upgrade to Drools 5 - loss of performance
Hi Scott, All I can say is I am glad to hear. :) Regarding your eclipse problem, please check 2 things: Drools plugin now supports multiple runtimes the same way that eclipse supports multiple JDKs. So, go to windows-preferences-drools-installed runtime to configure that. Also, make sure you are using eclipse 3.4. I believe this is in the drools plugin docs, but I did not checked myself.

[rules-users] Upgrade to Drools 5 - loss of performance
I just upgraded our app from Drools 4 to 5 libraries. We just use the rules engine with DRL. The performance of the engine on our rulebase is unacceptably slow. I assume there is something we need to do to our rules or the way we are configuring the engine to fix this. I don't see anything in the release notes about backwards compatibility issues. I would very much appreciate it if someone would direct me to any documentation that explains what needs to be done so our 4.0 rules perform at least as well as they did before the upgrade?

Re: [rules-users] Upgrade to Drools 5 - loss of performance
During a few experiments I did with MVEL, I have found that 2.x actually performs slower than 1.x in our case. Maybe that is a starting point. Scott, do you have the possibility to profile your application using 4.x and using 5.x? That should reveal the bottlenecks and I am sure that the dev crowd would be glad receiving that input. -- Ingomar Am 28.05.2009 um 17:18 schrieb Scott Reed: I just upgraded our app from Drools 4 to 5 libraries.

We have other users, who did get involved in this, saying we are faster for their use case. There are some use cases where 5 is slower, but it should be marginally slow, but it's scalability should be better for more facts and facts with larger number of fields. Could you produce a self contained project, with a unit test, that demonstrates this unnacceptable behaviour?

Re: [rules-users] Upgrade to Drools 5 - loss of performance
Scott, As others already mentioned, your e-mail does not help much. We need to know what is unacceptably slow. How much slower is that? 10%, 100%, 1000%? Also, we need a description of your use case: what kind of rules do you use, how many rules, how many facts, etc. Finally, we need a way to reproduce the problem.

Re: [rules-users] Upgrade to Drools 5 - loss of performance
Edson, I figured I must have missed some docs explaining changes required for the upgrade. If I suspected this was an inherent problem with the 5.0 release I'd have supplied lots of info. I am inferring from the response that there are no known issues with 5.0 upgrade so I'll do my own investigation for a while. Let's hope I find something unrelated to the Drools.

Re: [rules-users] Upgrade to Drools 5 - loss of performance
Indeed, at this point we are not aware of any performance problems. Of course all the features we added may add a bit of overhead, but in our tests that was completely offset by the improvements we made. The elimination of shadow facts by itself is a huge boost for use cases with lots of facts or facts with many fields. (just to mention one case) Keep us posted and if you submit more info, please include the actual versions of the jars you are using of Drools and MVEL.

Re: [rules-users] Upgrade to Drools 5 - loss of performance
Mark, I'm sorry I was unable to participate in pre-release testing. I didn't think we had an especially unusual application. It's under 100 rules with some simple evals and moderate processing on the consequence side. I'll try Ingomar's suggestion and get profiles and, if necessary, I'll pack it up send it to you.
