ADF features to improve performance of applications

Question

Hello,
While trying to find a fix for my application (built using ADF and JSF) which is very, very slow I came across this article on Oracle site and the suggestions were:
1. In web.xml, disable oracle.adf.view.faces.CHECK_FILE_MODIFICATION. I know in my application it is set to True, because I get the warning that this option should not be used in Production environment. But when I saw Web.xml, I did not see any mention of this property.
2. In web.xml, disable oracle.adf.view.faces.DEBUG_JAVASCRIPT. See my web.xml below, it does not even mention this property.
3. In adf-faces-config.xml, set <debug-output> to false. See my adf-faces-config.xml below, it does not even mention this property.
Any other thing that you see (or not see) that could enhance performance?

In the prod. environment CHECK_FILE_MODIFICATION has to be set to false.
    <context-param>
        <description>If this parameter is true, there will be an automatic check of the modification date of your JSPs, and saved state will be discarded when JSP's change. It will also automatically check if your skinning css files have changed without you having to restart the server. This makes development easier, but adds overhead. For this reason this parameter should be set to false when your application is deployed.</description>
        <param-name>org.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION</param-name>
        <param-value>false</param-value>
    </context-param>It's there in v2.5
