Hi! I'm currently working on a big page displaying a topic and every of its children hierarchically. Since these topics can have a lot of children, I figured out I should cache my page to enhance my performances.
I actually managed to cache it, jumping from a poor 40s~ page generation time to a big but-still-not-great enhancement to 6s. I actually don't understand why it takes so much time, since as far as I understood, the whole page should be cached, so it should basically result to a 'static page', ie. almost an instant loading. Here's the code: <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> | <ui:composition xmlns="http://www.w3.org/1999/xhtml"; | xmlns:s="http://jboss.com/products/seam/taglib"; | xmlns:ui="http://java.sun.com/jsf/facelets"; | xmlns:f="http://java.sun.com/jsf/core"; | xmlns:h="http://java.sun.com/jsf/html"; | xmlns:rich="http://richfaces.ajax4jsf.org/rich"; | xmlns:a4j="https://ajax4jsf.dev.java.net/ajax"; | xmlns:c="http://java.sun.com/jstl/core"; | template="/layout/template.xhtml"> | | | <ui:define name="body"> | <s:cache key="#{topicHome.instance}" region="/Topic" enabled="true"> | <h:form> | <s:link value="#{messages['lrb.message.back_to_main_list']}" view="/Thesaurus.xhtml"/> | <h:outputText value=" | " /> | <h:inputText value="#{searchTopic}" /> | <h:commandButton value="#{messages['lrb.action.search']}" | action="#{thesaurusManager.searchTopic()}" /> | <br /> | <br /> | <h:commandLink action="#{thesaurusManager.showTopic(topicHome.instance)}" | value="#{topicHome.instance.name}" /> | <h:commandLink | action="#{thesaurusManager.selectTopic(topicHome.instance)}" | value="(#{topicHome.instance.relatedBooks} #{messages['lrb.thesaurus.hits']})" | rendered="#{topicHome.instance.relatedBooks.intValue() != 0}" /> | <br /> | <ui:include src="/layout/alphabetLinks.xhtml"/> | <br /> | <ul> | <table id ="thesaurusResultTable"> | <tr> | <c:forEach items="#{topicHome.instance.sortedColumnedChildren}" | var="superList"> | <td> | <c:forEach items="#{superList}" var="list"> | <c:forEach items="#{list}" var="t"> | <a name="#{t.name.substring(0,1)}" /> | <f:subview > | <li><s:link view="/showTopic" value="#{t.name}" propagation="nest"> <f:param name="topicId" value="#{t.id}" /> </s:link> | (<s:link value="#{t.relatedBooks} #{messages['lrb.thesaurus.hits']}" view="/showBooks" propagation="nest"> <f:param name="topicId" value="#{t.id}"/> </s:link>)</li> | <ui:include src="/showChild.xhtml"> | <ui:param name="topic" value="#{t}" /> | </ui:include> | </f:subview> | </c:forEach> | <br /> | </c:forEach></td> | </c:forEach> | | </tr> | </table> | | </ul> | </h:form> | </s:cache> | </ui:define> | | </ui:composition> | This page is the main one, the one I surrounded with s:cache tag. Then showChild is called recursively to load every children: | <c:forEach items="#{topic.children}" var="t"> | <f:subview> | <ul> | <li><s:link view="/showTopic" value="#{t.name}" propagation="nest"> <f:param name="topicId" value="#{t.id}" /> </s:link> (<s:link value="#{t.relatedBooks} #{messages['lrb.thesaurus.hits']}" view="/showBooks" propagation="nest"> <f:param name="topicId" value="#{t.id}"/> </s:link>)</li> | | <ui:include src="/showChild.xhtml"> | <ui:param name="topic" value="#{t}" /> | </ui:include> | | </ul> | </f:subview> | </c:forEach> Then, finally, my treecache.xml config file: | <?xml version="1.0" encoding="UTF-8"?> | | <!-- ===================================================================== --> | <!-- --> | <!-- PojoCache Service Configuration --> | <!-- --> | <!-- ===================================================================== --> | | <server> | | <!-- Used inside JBoss AS | <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/> | --> | | <!-- ==================================================================== --> | <!-- Defines configuration --> | <!-- ==================================================================== --> | | <mbean code="org.jboss.cache.aop.PojoCache" name="jboss.cache:service=testPojoCache"> | | <!-- Used inside JBoss AS --> | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | | <!-- | Configure the TransactionManager | <attribute name="TransactionManagerLookupClass">org.jboss.cache.DummyTransactionManagerLookup</attribute> | --> | | <!-- | Node locking scheme: | OPTIMISTIC | PESSIMISTIC (default) | --> | <attribute name="NodeLockingScheme">PESSIMISTIC</attribute> | | <!-- | Note that this attribute is IGNORED if your NodeLockingScheme above is OPTIMISTIC. | | Isolation level : SERIALIZABLE | REPEATABLE_READ (default) | READ_COMMITTED | READ_UNCOMMITTED | NONE | --> | <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | | <!-- | Valid modes are LOCAL | REPL_ASYNC | REPL_SYNC | INVALIDATION_ASYNC | INVALIDATION_SYNC | --> | <attribute name="CacheMode">LOCAL</attribute> | | <!-- Name of cluster.

Thanks for your help.
