Performance improvement in JSF2

Recently, I come across performance issues with JSF2. The challenge was to improve the time response for rendering the page. I am here with configuration of jsf2 parameters, which helped us to reduce the time response to render the page contents,

Set the state method as server.

        <context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>server</param-value>
</context-param>

Limit the number of views in session to small number.

    <context-param>
            <param-name>org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION</param-name>
            <param-value>15</param-value>
    </context-param>

Don't serialize the state, set the compress state as false
    <context-param>
        <param-name>org.apache.myfaces.SERIALIZE_STATE_IN_SESSION</param-name>
        <param-value>false</param-value>
    </context-param>


    <context-param>
        <param-name>org.apache.myfaces.COMPRESS_STATE_IN_SESSION</param-name>
        <param-value>false</param-value>
    </context-param>
    <context-param>
        <param-name>org.apache.myfaces.PRETTY_HTML</param-name>
        <param-value>false</param-value>
    </context-param>


cache the el-expressions
    <context-param>
        <param-name>org.apache.myfaces.CACHE_EL_EXPRESSIONS</param-name>
        <param-value>always</param-value>
    </context-param>
    <context-param>
        <param-name>org.apache.myfaces.CHECK_ID_PRODUCTION_MODE</param-name>
        <param-value>false</param-value>
    </context-param>



below parameters are added to not refresh facelets for static pages
    <context-param>
        <param-name>javax.faces.FACELETS_REFRESH_PERIOD</param-name>
        <param-value>-1</param-value>
    </context-param>
    <context-param>
        <param-name>facelets.REFRESH_PERIOD</param-name>
        <param-value>-1</param-value>
    </context-param>
