Hi, I already posted this message in the Seam forums, but I figured it was most probably a topic that would fit here.
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. Thanks to a sysout, I've also noticed that when a cached page is rendered, my backing bean is being used! 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: 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()}" /> <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}" /> <ui:include src="/layout/alphabetLinks.xhtml"/> <c:forEach items="#{topicHome.instance.sortedColumnedChildren}" var="superList"> <c:forEach items="#{superList}" var="list"> <c:forEach items="#{list}" var="t"> <f:subview > <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>) <ui:include src="/showChild.xhtml"> <ui:param name="topic" value="#{t}" /> </ui:include> </f:subview> </c:forEach> </c:forEach> </c:forEach> </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: Code: <c:forEach items="#{topic.children}" var="t"> <f:subview> <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>) <ui:include src="/showChild.xhtml"> <ui:param name="topic" value="#{t}" /> </ui:include> </f:subview> </c:forEach> Then, finally, my treecache.xml config file: Code: <?xml version="1.0" encoding="UTF-8"?> <!-- ===================================================================== --> <!-- --> <!-- PojoCache Service Configuration --> <!-- --> <!-- ===================================================================== --> <!-- Used inside JBoss AS --> <!-- ==================================================================== --> <!-- Defines configuration --> <!-- ==================================================================== --> <!-- Used inside JBoss AS --> jboss:service=Naming jboss:service=TransactionManager <!-- Configure the TransactionManager org.jboss.cache.DummyTransactionManagerLookup --> <!-- Node locking scheme: OPTIMISTIC PESSIMISTIC (default) --> PESSIMISTIC <!-- Note that this attribute is IGNORED if your NodeLockingScheme above is OPTIMISTIC.
