Ara Minosian commented on RF-10259:
-----------------------------------

I think a lot of users as me will check different component libraries for speed. This enhancement can cause RichFaces to look faster than other, and this really should be, because you spend especial time for GAE.

> I found a way to reduce JSF based application to start faster on GAE.
> 1. Register all managed beans statically in faces-config.xml 
> 2. Use metadata-complete="true" attribute, so faces-config.xml boilerplate is:
> <?xml version='1.0' encoding='UTF-8'?>
> <faces-config xmlns="http://java.sun.com/xml/ns/javaee"
>               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>               xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
>               http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
>               version="2.0"
>               metadata-complete="true">
>     
> <!--Your stuff here-->
> </faces-config>
> Using this technique you force JSF not to scan classes for beans. You can leave bean annotations in source code for user's clarity. It will not produce any error.
> 3. Force JSF not to check xml syntax. I hope IDE do it instead. In web.xml set context parameter as here:
> <context-param>
>      <description>
>          Set this flag to true if you want the JavaServer Faces
>          Reference Implementation to validate the XML in your
>          faces-config.xml resources against the DTD. Default
>          value is false.
>      </description>
>      <param-name>com.sun.faces.validateXml</param-name>
>      <param-value>false</param-value>
> </context-param> 
> Using these tricks I reduce GAE start time by two seconds. Not bad.
