512 Mo for your JVM is not enough !

 

upgrade RAM to 2Go at least on your server and move your PostgreSQL DB on an other computer

 

replace your jvm options by -Xms512Mo -Xmx1536Mo (You're on 32bits archi, so the JVM can't use more than 1.5Go RAM)

 

on the tomcat conf/web.xml use this options for the "jsp" servlet

 

    <servlet>

        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>logVerbosityLevel</param-name>
            <param-value>ERROR</param-value>
        </init-param>

             <param-value>false</param-value>

             <param-value>false</param-value>
         </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>

First: I created the index from Jahia Clustering How-to documentation. Second: I already run vaccumdb once a day. Third: I already created the special index for the most used queries/tables My DB and Jahia area on the same computer. These are the options tha I use in catalina.sh: JAVA_OPTS="-Dfile.encoding=ISO-8859-1 -Xms128M -Xmx512M -server -XX:MaxHeapFreeRatio=70 -XX:MinHeapFreeRatio=40 -XX:+UseConcMarkSweepGC" > 2005/10/8, Ghislain CUSSONNEAU <[EMAIL PROTECTED]>: Fisrt : create the index from Jahia Clustering How-to documentation. Second : Run the vaccumdb command (in postgresql bin folder) every day/week you made changes on your sites that optimize index usage Third : run on the SQL log on postgresql to find which queries/tables are the most used and create special index for them. Is your DB and Jahia on the same computer ?

I didn't set MaxHeapSize but I set MaxHeapFreeRatio=70 MinHeapFreeRatio=40.
