[rules-users] High Performance Rules Environment

[Edson Tirelli]

    Robert,

    This is a very complex evaluation to do, since most of the published
benchmarks will give you different results for the same rules engine. :)
Also, the first and third links you listed bellow, all refer to Drools
2.xseries that were not Rete complete implementations. Just to show
you the
difference between drools 2.x and 3.x, check this:

http://blog.athico.com/2006/11/rush-hour-and-content-based-routing.html

    Drools 4.x is even faster for complex rules scenarios with lots of
partial matches.

    The testimonies though are good for you to check out as they are recent
testimonies.

    Best thing to do would be, if possible, to build a prototype with a use
case closer to what you need and check the numbers out. We are sure that on
a face to face performance comparison, you will be pleasant surprised with
the power of the Drools rules engine.

    If you need help on the prototype, just mail the list, or if you want
official support for it, just contact Red Hat.

    Regards,
       Edson
