richfaces modal panel perfromance

[betul aydin]

hi I have got a performance problem in my simple application.
It takes too long to open the ModalPanel, if the page contains many HTML-Elements (ie DataTable with 600 columns and 15 rows).
How can I repair modal panel performace .Can anybody give me suggestion about this.here is my code about modal panel

   

  <rich:dataTable  width="900" id="detayEkstre" value="#{HesapIslem.hdetaytablo}"   rowClasses="row1,row2"  var="detay"  onRowMouseOver="this.style.backgroundColor='#F2F7CC'" onRowMouseOut="this.style.backgroundColor=''"  rowKeyVar="row"  >
					 
             ***********************

<rich:column  width="15" >				  	
    <a4j:region>
        <a4j:commandButton id="kimkontrol" action="#{HesapIslem.KimKontrol}" rendered="#{detay.kontrol=='true'}" image="/img/p.png" style=" width : 12px;" reRender="detay,panel,kim,kont" oncomplete="javascript:Richfaces.showModalPanel('panel')">
		 <f:setPropertyActionListener value="#{row}" target="#{HesapIslem.rowindex}" />
     </a4j:commandButton>	
 </a4j:region>         

   </rich:column>   

**********************************
  </rich:dataTable>      

<rich:modalPanel id="panel" autosized="true">
                <f:facet name="header">
                    <h:outputText value="Onay/Kontrol Bilgileri"></h:outputText>
                </f:facet>
         <a4j:form id="kim">
           <a4j:outputPanel id="kont" >
           
           <h:panelGrid    columns="2" style="margin-top:6px; margin-bottom:10px;  " width="300"  >            
               <h:outputText value="Kontrol Eden:" styleClass="label" /> <h:outputText  value="#{HesapIslem.kontroleden}" />        
               <h:outputText value="Kontrol Tarihi:" styleClass="label" /> <h:outputText  value="#{HesapIslem.kontroltarih}"  />                
           </h:panelGrid>
           
           <h:panelGrid id="on" rendered="#{HesapIslem.onayPanel}" columns="2" style="margin-top:6px; margin-bottom:10px;  " width="300"  >

           </h:panelGrid>
          </a4j:outputPanel> 
		               
           <a4j:commandButton value="Çıkış"  reRender="panel"  styleClass="button"   onclick="javascript:Richfaces.hideModalPanel('panel')" ></a4j:commandButton>		 
		</a4j:form>
        </rich:modalPanel>

A datatable with 600 columns is a performance problem even without a modal panel. That's a lot of data to dump on a single page. Is there a more manageable way of presenting that information?
