    Bad ModalPanel performance (RF-3670)

      Hi all,

      i'm having performance problem with ModalPanel on my application, so i made a simple project to test its performance "isolatedly" (sorry about my english).
      Then i noted that the time to open and close the modal increases according the number of rendered components in my page. Here is my relevant test code:


      <body>
      
      <rich:modalPanel id="mpDefault" resizeable="false" autosized="true">
       <h:form id="formModalPanel">
       <a4j:outputPanel id="opModalPanel" ajaxRendered="true">
       <rich:panel id="pnModalPanel" binding="#{testModalPanel.pnModalPanel}" />
       </a4j:outputPanel>
       </h:form>
      </rich:modalPanel>
      
      <h:form id="startForm">
      
      <a4j:commandButton value="show modal" oncomplete="Richfaces.showModalPanel('mpDefault');" />
      
      <rich:panel id="pnPanel" binding="#{testPanel.pnPanel}" />
      
      </h:form>
      


      public class TestModalPanel {
      
       private HtmlPanel pnModalPanel;
      
       public TestModalPanel() {
       pnModalPanel = new HtmlPanel();
       pnModalPanel.setStyle("background-color: blue; height: 200px; width: 200px; text-align: center;");
      
      
       HtmlAjaxCommandButton btClose = new HtmlAjaxCommandButton();
       btClose.setValue("fechar");
       btClose.setOncomplete("Richfaces.hideModalPanel('mpDefault');");
       pnModalPanel.getChildren().add(btClose);
       }
      
       public HtmlPanel getPnModalPanel() {
       return pnModalPanel;
       }
      
       public void setPnModalPanel(HtmlPanel pnModalPanel) {
       this.pnModalPanel = pnModalPanel;
       }
      
      }
      



      public class TestPanel {
      
       private HtmlPanel pnPanel;
      
       public TestPanel() {
       this.pnPanel = new HtmlPanel();
       this.pnPanel.setStyle("height: 400px; width: 800px; margin-left: auto; margin-right: auto; background-color: yellow; overflow: auto;");
      
       HtmlPanel pn = null;
       HtmlOutputText ot = null;
       HtmlInputTextarea ta = null;
       HtmlInputText it = null;
      
       for (int i=0, iLen=1000; i<iLen; i++) {
       pn = new HtmlPanel();
       pn.setId("pn"+i);
       pn.setStyle("width: 100%; height: 100px;");
      
       ot = new HtmlOutputText();
       ot.setId("ot"+i);
       ot.setValue("HtmlOutputText ["+i+"]");
       pn.getChildren().add(ot);
      
       ta = new HtmlInputTextarea();
       ta.setId("ta"+i);
       pn.getChildren().add(ta);
      
       it = new HtmlInputText();
       it.setId("it"+i);
       pn.getChildren().add(it);
       this.pnPanel.getChildren().add(pn);
       }
       }
      
       public HtmlPanel getPnPanel() {
       return pnPanel;
       }
      
       public void setPnPanel(HtmlPanel pnPanel) {
       this.pnPanel = pnPanel;
       }
      
      }
      


      With the iLen=1000, the Modal takes around 8s to open and 4s to close. If i set iLen=1, the Modal takes less than 1s to open or close.
      I found some posts with same problem, and some reported bugs too.

      http://jira.jboss.com/jira/browse/RF-3670
      http://jira.jboss.com/jira/browse/RF-3572

      Is this a bug? Am i doing something wrong? Any tip to increase the performance?

      My setup:
      Apache Tomcat/6.0.14
      rf3.2.2 GA
      IE 7 and FF2.0

      Thanks a lot.






        • 1. Re: Bad ModalPanel performance (RF-3670)

          Accidentaly i discovered an interesting behaviour. Maybe the problem is not with the ModalPanel. I made another test, very simple too.
          I have an <a4j:commandButton> and a <h:outputText>. Every time i click on the button, the outputText shows current Date in ms. Please take a look at my code:

          <a4j:commandButton value="test rerender" limitToList="true" actionListener="#{testPanel.buttonClicked}" reRender="otStatus" />
          
          <h:outputText id="otStatus" value="#{testPanel.txtStatus}"/>
          


          public void buttonClicked(ActionEvent event) throws Exception {
           long now = new Date().getTime();
           this.setTxtStatus(now+"");
          }
          


          I'm still using the previous post loop to create some components. If i set iLen=1, the outputText content changes immediately. But, if i set iLen=1000, it takes at least 4s to change.
          Again, the performance decreases if i have "lot" of components in the page.
          Is there something wrong in my code? What should i change to have a best performance?
          Thanks for any help.

            ok.. please add ajaxSingle="true" to your commang button which opens a modal. This is not modal panel question. The time lost at server side. Many components in component tree and all of them will be decoded and processed as for normal request (non ajax) if you will not limit this with ajaxSingle or region.

            • 3. Re: Bad ModalPanel performance (RF-3670)

              Thanks for the answer ilya. I made the change but the performance continues the same. Here is the new code:

              <rich:modalPanel id="mpDefault" resizeable="false" autosized="true">
               <h:form id="formModalPanel">
               <a4j:outputPanel id="opModalPanel" ajaxRendered="true">
               <rich:panel id="pnModalPanel" binding="#{testModalPanel.pnModalPanel}" />
               </a4j:outputPanel>
               </h:form>
              </rich:modalPanel>
              
              <h:form id="startForm">
              
              <a4j:commandButton value="show modal" oncomplete="Richfaces.showModalPanel('mpDefault');" ajaxSingle="true"/>
              
              <rich:panel id="pnPanel" binding="#{testPanel.pnPanel}" />
              
              </h:form>
              


              Maybe some problem with my web.xml?

                    • 7. Re: Bad ModalPanel performance (RF-3670)

                      If i change the STATE_SAVING_METHOD from "client" to "server", the performance increases a little, but the ModalPanel still takes a good seconds to open and close.

                      <context-param>
                       <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
                       <param-value>server</param-value>
                      </context-param>
                      


                      • 8. Re: Bad ModalPanel performance (RF-3670)

                        I hosted a test application at
                        http://200.169.232.139/test_rf
                        to demonstrate the performance of ModalPanel.
                        When you click populate, it populates a yellow panel with 1000 panels. Clear button clears the panel. Show modal panel opens the Modal panel. The time to open and close the Modal Panel variates accordng the number of components in yellow panel.
                        I'm using STATE_SAVING_METHOD "server", just because it increases the performance, but i don't know the complications of it. I think it could be a problem when the user quantity grow. Am i wright?
                        I made some modifications at my code too. Here is the last version of relevant code.

                         ot.setValue("HtmlOutputText ["+i+"]");
                         pn.getChildren().add(ot);
                        
                         ta = new HtmlInputTextarea();

                         }
                        


                        The server config:
                        Sun Java System Application Server 9.1_02 (build b04-fcs)
                        Intel Xeon 3065
                        2GB RAM

                        Can i do any other change in my code to increase the performance? Thanks a lot. [/url]

                          It takes about 3s to open and lesser that 1s to close for me using test you created.

                          • 10. Re: Bad ModalPanel performance (RF-3670)

                            Have you tested on FF 2? Please try it at IE.
                            On my IE7 test, it takes about 7s to open and 2s to close. Is this a IE bug?
                            But, anyway, why the performance of modalpanel is associated with the other components of the page?
                            If i use ajaxSingle="true" limitToList="true" and reRender="mpDefault", the other components should not take influence over Modal Panel. Wright?

                              If i use ajaxSingle ("boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only"), is necessary the use of <a4j:region>?
