Investigate performance delta with MR3 and 3.0.6
------------------------------------------------

                 Key: JBRULES-959
                 URL: http://jira.jboss.com/jira/browse/JBRULES-959
             Project: JBoss Rules
          Issue Type: Task
      Security Level: Public (Everyone can see)
          Components: All
    Affects Versions:  4.0.0.MR3
            Reporter: Michael Neale
         Assigned To: Michael Neale


// 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());
 
// 3.0.6's performance: 12:09:40,446 INFO  [RuleLoadBean] Average rule execution time in ms: 0.7726
 
// What is measured:
 
ruleBase = rsl.getGroupRuleBase(group); // That retrieves the RuleBase from the cache
 
WorkingMemory wm = ruleBase.newWorkingMemory();
for (Iterator j = toBeAsserted.get(group.getId()).iterator(); j.hasNext();)
	wm.assertObject(j.next());
wm.fireAllRules();
