> // Rule execution time test
> // I give the DRL one fact of class BOBOMessage (made final due to Michael's suggestion)
> // The "message" member of my BOBOMessage fact contains a random combination of the keywords the rule is designed to match
> // A random BOBOMessage like that is generated before every execution

> // MR3's performance: 11:43:01,135 INFO  [RuleLoadBean] Average rule execution time in ms: 2.3991

> // What is measured:
> ruleBase = rsl.getGroupRuleBase(group); // That retrieves the RuleBase from the cache
>  
> StatelessSession session = ruleBase.newStatelessSession();
> session.execute(toBeAsserted.get(group.getId()).toArray());
