[rules-users] Upgrade to Drools 5 - loss of performance

[Edson Tirelli]

   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.

   So, if you can provide more info, we might be able to help.
