CBR using rules has poor performance ------------------------------------ Key: JBESB-2152 URL: https://jira.jboss.org/jira/browse/JBESB-2152 Project: JBoss ESB Issue Type: Bug Security Level: Public (Everyone can see) Components: Content Based Routing Affects Versions: 4.2.1 Environment: SOA-P 4.2.0.beta1 Reporter: Martin Vecera Assignee: Daniel Bevenius Fix For: 4.4 We have a simple performance that uses ContentBasedRouter to route XML messages: <action class="org.jboss.soa.esb.actions.ContentBasedRouter" name="ContentBasedRouter"> <property name="ruleSet" value="MyESBRules-XPath.drl"/> <property name="ruleLanguage" value="XPathLanguage.dsl"/> <property name="ruleReload" value="true"/> <property name="destinations"> <route-to destination-name="regular1" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular2" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular3" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular4" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular5" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular6" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular7" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular8" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular9" service-category="wiretapCategory1" service-name="regularService"/> <route-to destination-name="regular0" service-category="wiretapCategory1" service-name="catchService"/> </property> </action> I have created a rule set of 100 rules. Like this: package com.jboss.soa.esb.routing.cbr import org.jboss.soa.esb.message.Message; import org.jboss.soa.esb.message.format.MessageType; expander XPathLanguage.dsl global java.util.List destinations; rule "ProductId1" salience 100 when xpathEquals "/Order/OrderLines/OrderLine/Product/@productId", "1" then Destination : "regular1"; end ... rule "ProductId299" salience 100 when xpathEquals "/Order/OrderLines/OrderLine/Product/@productId", "299" then Destination : "regular0"; end rule "Default rule" salience 1 when then Destination : "regular0"; end See https://svn.corp.jboss.com/repos/soa/trunk/qa/tests/quickstarts/performan... for the whole file. The performance is very poor (see SOA-240 for reports). Only a tens of messages per second. What's the problem here? Is the Rules engine really so slow? Or is it parsing the file every time a message arrives? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
