[jboss-jira] [JBoss JIRA] (DROOLS-5108) KieHelper.build is very slow on Drools 6.4.0.Final

Mario Fusco resolved DROOLS-5108.
---------------------------------
    Resolution: Out of Date


6.4.0.Final is 4 years old and of course we cannot provide community support for a so old release. Please try with a more recent one. Also claiming that X is "slow" while doing Y is not something workable. First of all you should provide a complete reproducer to allow us to benchmark and profile your specific situation. Second generically saying that it is "slow" isn't an objective measure. What are your expectations? What is a value acceptable for you and under which threshold you will stop considering this "slow"?
