Performance Problem

[labian]

I have the following code:

<f:view>
<h:form>
<a4j:region renderRegionOnly="true" >
<h:inputText id="text" value="#{bean.text}"
validator="#{bean.validate}" valueChangeListener="#{bean.onChange}">
<a4j:support event="onkeyup" ajaxSingle="true"></a4j:support>
</h:inputText>
</a4j:region>

</h:form>
</f:view>

I am measuring the content length and the time request, and when increase the number of controls in the page (For example):

<f:view>
<h:form>
<a4j:region renderRegionOnly="true" >
<h:inputText id="text" value="#{bean.text}"
validator="#{bean.validate}" valueChangeListener="#{bean.onChange}">
<a4j:support event="onkeyup" ajaxSingle="true"></a4j:support>
</h:inputText>
</a4j:region>


<a4j:region>
<a4j:repeat value="#{repeatData.data}" var="row">
<h:inputText id="repeattext" value="#{row.text}"
validator="#{bean.validate}" valueChangeListener="#{bean.onChange}">
<a4j:support event="onkeyup" ajaxSingle="true"></a4j:support>
</h:inputText>
<a4j:outputPanel ajaxRendered="true">
<h:outputText value="#{row.text}"></h:outputText>
<h:message for="repeattext"></h:message>
</a4j:outputPanel>
</a4j:repeat>
</a4j:region>
<a4j:region>
<a4j:repeat value="#{repeatData.data}" var="row">
<h:inputText id="repeattext" value="#{row.text}"
validator="#{bean.validate}" valueChangeListener="#{bean.onChange}">
<a4j:support event="onkeyup" ajaxSingle="true"></a4j:support>
</h:inputText>
<a4j:outputPanel ajaxRendered="true">
<h:outputText value="#{row.text}"></h:outputText>
<h:message for="repeattext"></h:message>
</a4j:outputPanel>
</a4j:repeat>
</a4j:region>
<a4j:region>
<a4j:repeat value="#{repeatData.data}" var="row">
<h:inputText id="repeattext" value="#{row.text}"
validator="#{bean.validate}" valueChangeListener="#{bean.onChange}">
<a4j:support event="onkeyup" ajaxSingle="true"></a4j:support>
</h:inputText>
<a4j:outputPanel ajaxRendered="true">
<h:outputText value="#{row.text}"></h:outputText>
<h:message for="repeattext"></h:message>
</a4j:outputPanel>
</a4j:repeat>
</a4j:region>

</h:form>
</f:view>



Also increases the size of the request. I am using a4j regions. Which can be the problem? In a request ajax always is sent all the components of the page?

Thanks in advance

anyone?

a4j:region - by default reduces only size of the tree that will be decoded. To reduce the size of the encoded responce set renderRegionOnly to true(updatable elements should be in the same reguon for this case).
