All- Yeah, there are a bunch of misinformed people who have made disparaging remarks about Drools on various blogs. Either they really haven't attempted to work with drools, or they simply read something negative that someone else wrote and accepted it as fact. In many cases, they are writing because they have an agenda to promote some other commercial or open-source product.
It is conspicuous that these bloggers rarely have anything by way of contrast or comparison to say that demonstrates that their favorite solution is fundamentally superior. In the rare case, that there are comments that assert that a particular product may be superior to DROOLS, it is rare that they have done a good job of researching the differences. Perhaps the one area that Drools does not compare favorably against commercial products is the lack of a GUI front end and in the lack of an integrated tool to easily manage rules repositories (although that will probably be forthcoming now that DROOLS is part of JBOSS). That said, I would urge people to look at the commercial products and realize that there are certain hoops that you need to jump through to utilize the rule repositories and operate within the UI -- trust someone who has worked with a variety of these products, it's no picnic working with the commercial products, and you typically have a 1/4 M$ entry fee (generally much higher than that) for even a pilot project. That's not to say that certain rules engines might not be a better fit for some projects than others, but I think that the analysis that is needed to compare the advantages and disadvantages of one engine over another is much, much more than what these bloggers have shown. - Dave -----Original Message----- From: Felipe Piccolini [mailto:[EMAIL PROTECTED] Sent: Thursday, November 03, 2005 2:30 PM To: [email protected] Subject: [drools-user] Comment on drools performance. Guys, In this link a guy comment on Drools's performance and some people in my company are worried about the impact this can produce on the application (beacuse of course I introduced Drools on it). I know this is not a real problem, and we are using rule engine in a smart way so working memory and rules are no over loaded, but the top managers need more facts than just my opinion, and Im asking all of you guys about experiences and real comments about this link and about your application performance and scalability using Drools. http://bizrules.eclipsedevelopersjournal.com/some_thoughts_about_drools. htm Thaks a lot. ---------------------- Felipe Piccolini [EMAIL PROTECTED]
