---------------------------------------

I tried your PR and the results are similar to yours. So I agree that this should be closed. I created a long term JIRA for better enhancement here: https://issues.jboss.org/browse/DROOLS-1495.

> From doc [1] there can be seen that four benchmarks show problems when run with parallel agenda enabled. 
> Benchmarks _AdvOperators3ExpertBenchmark_ and _RetractFactsFromWmExpertBenchmark_ 
> falled back to single threaded agenda although they doesn't use features that aren't supported with parallel agenda (e.g. like salience). 
> Benchmarks StartsStartedbyFusionBenchmark and UpdateFactsInWmExpertBenchmark shows no gain when using parallel agenda although they contain more partitions. 
> I created runners for debugging here [2], so the benchmarks can be debugged outside of JMH. They are part of master branch in kie-benchmarks, so just pull of new changes is sufficient to get them.
