<span style="background:white">Let me explain one more time, our performance issue. We have done fresh Geonode 2.6.2 installation (standard deployment), give VM 24GB RAM and 12 CPU. After installation, we have done:</span><br>
<span style="background:white">1) Replace OpenJVM with OracleJVM </span><br>
<span style="background:white">2) We've increased the JVM memory by adding into /etc/default/tomcat7 </span><br>

<span style="background:white">3) Enable Native JAI and Native JAI ImageIO</span><br>
<span style="background:white">4) Enable Tile caching into External PostgreSQL database</span><br>
<br>
<span style="background:white">Additionally, we have tried the following:</span><br>
<span style="background:white">1) In /etc/tomcat7/server.xml added maxThreads="50":</span><br>
<span style="background:white"> </span><br>
<span style="background:white"> <Connector port="8080" protocol="HTTP/1.1"</span><br>

<span style="background:white"> URIEncoding="UTF-8"</span><br>
<span style="background:white"> redirectPort="8443" maxThreads="50"/></span><br>
<span style="background:white">2) In /etc/apache2/mods-enabled/mpm_event.conf</span><br>
<br>
<span style="background:white">try to change conf parameters with no results:</span><br>
<span style="background:white"><IfModule mpm_event_module></span><br>
<span style="background:white"> StartServers 2</span><br>
<span style="background:white"> MinSpareThreads 25</span><br>

<span style="background:white"> ThreadLimit 64</span><br>

<span style="background:white"> MaxRequestWorkers 150</span><br>
<span style="background:white"> MaxConnectionsPerChild 0</span><br>
<span style="background:white"></IfModule></span><br>
<br>
<span style="background:white">Still, when 4-5 clients try to render maps, performance radically decrease and geonode become unresponsive.</span><br>
