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();
