Render response Performance

[lmk]

Hi all,

Im using <h:commandButton/> and a4j:support, for navigation. the page takes a long time to be rendered.
the page contains
1) panel grid
2)3 rich:panels : each rich:panel contains many comboBox

the code for navigation is:

<rich:tab label="one" id="menu_tab"
 name="#{menu.OnetabName}" action="index" disabled="#{menu.disabledOne}">
<h:commandButton value="Quick Search" action="search"
styleClass="#{menu.viewUsersStyle}" immediate="true" disabled="#{menu.disabledSearch}">
<a4j:support event="onclick"
 actionListener="#{menuManager.viewManageUsersControl}" ajaxSingle="true" process="menu_tab">
</a4j:support>
</h:commandButton>

..
..
</rich:tab>

Best regards!

Hello,

First of all, please try to remove nested a4j:support from h:commandButton. This combination leads to two parallel requests (as you can see in phase tracker log) and is not correct. You can use a4j:commandButton instead.

I changed h:commandButton to a4j:commandButton, and it still takes more than 2 secondes

Ok, just to clarify: you have single a4j:commandButton and no a4j:support inside of it, right?

You can try changing parsers: http://www.jboss.org/file-access/default/members/jbossrichfaces/freezone/docs/devguide/en/html/ArchitectureOverview.html#FilterConfiguration; Tidy (the slowest one) is used by default. Try NEKO or NONE

No I know, I never use a4j:support inside a4j:commandButton..

<a4jcommandButton value="Quick Search" action="search"
styleClass="#{menu.viewUsersStyle}"
immediate="true" disabled="#{menu.disabledSearch}"
actionListener="#{menuManager.viewManageUsersControl}" process="menu_tab"/>

[nbelaevski]

That's right. Please try changing parsers then.

it's what Im doing

<context-param>
 <param-name>org.ajax4jsf.xmlparser.ORDER</param-name>
 <param-value>NONE,NEKO,TIDY</param-value>
 </context-param>

 <context-param>
 <param-name>org.ajax4jsf.xmlparser.NEKO</param-name>
 <param-value>/query.xhtml,/result.xhtml</param-value>
 </context-param>

it's that enough ou should I add ohter parameter?

[nbelaevski]

Dot ('.') should be escaped, as parameter value is interpreted as regular expression. Also you can configure parsers order without specifying org.ajax4jsf.xmlparser.NEKO parameter; org.ajax4jsf.xmlparser.ORDER is applied to all views by default.
