<div class="m_-18108789137461379m_6251474185786257327moz-cite-prefix">Dear John,<br>
<br>
We have in-house server on the corporate LAN (100Mbps). We have tested bandwidth speed with iperf. We have started iperf on 4 Windows clients and on Ubuntu/GeoNode Server. Every time all clients are sharing 100Mbps (cca 25Mbps per client). So, we think it is
not the network issue.<br>
<br>
We have installed fresh Geonode v2.6.2 on Ubuntu Server 16.04. In order to speed up system, we gave Geonode 24GB of RAM and 12 CPU. Virtualization platform is Oracle VM.<br>
In the moment when performance decrease, a server eats only 6-7GB of RAM (free is 17-18GB of RAM) and load average is about 7.<br>
<br>
We have enabled GeoWebCache by doing the following:<br>
- Caching to external postgresql database<br>
Tile caching - Disk quota....Enable disk Quota ....Maximum tile cache size 50GiB<br>
Disk quota check frequency:600s<br>
Disk quota store type....External database<br>
Target database type....PostgreSQL<br>
JDBC data source...GeoServer managed connection pool<br>
JDBC Driver class name.....org.postgresql.Driver<br>
JDBC connection URL.....jdbc:postgresql://loca<wbr>lhost:5432/geonode<br>
User name..... geonode<br>
Password.... ******<br>
Validation query.....select 1<br>
<br>
sudo service tomcat7 stop<br>
sudo service apache2 stop<br>
mkdir /var/cache/geoserver<br>
chmod -R 777 geoserver<br>
In:<br>
vi /usr/share/geoserver/WEB-INF/w<wbr>eb.xml<br>
added:<br>
<context-param><br>
<param-name>GEOWEBCACHE_CACHE_<wbr>DIR</param-name><br>
<param-value>/var/cache/geoser<wbr>ver/</param-value><br>
</context-param><br>
sudo reboot<br>
<br>
Here is the link of our map containing 140 internal layers (without external WMS layers) during heavy rendering of 4 clients:<br>

During online connection of Mr. Alessio Fabiani, he has made following changes:<br>
-Geofence:<br>

Cache refewsh interval: 600000<br>

<span>This recording was taken during of heavy map rendering of 4 clients. We have 144 vector layers and 2 external WMS layers (behaviour is the same
when we don't use WMS layers. In video link, we have used only local vector layers, not external WMS layers). We are not experienced enough to know what does cause the issue (GeoNode or GeoServer).<br>
Please reveive one typical kml layer in the attachment.</span><br>

<div dir="ltr">Can you please better explain what you mean with "Map Performance" exactly?
<div><br>
</div>
<div>Getting the list of layers or rendering the map?</div>
<div><br>
</div>
<div>Also, how many layers you have and which type (vectorial / raster) ?</div>
<div><br>
</div>
<div>Are you able to identify performance issues? Those are on GeoNode or GeoServer?</div>
<div><br>
</div>
<div>In the first case it is certainly an issue of your HTTP Server configuration (and most probably the proxy module), in the second case it could be an issue of data not correctly processed.</div>

<span>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>1) Replace OpenJVM with OracleJVM </span><br>
<span>2) We've increased the JVM memory by adding into /etc/default/tomcat7 </span><br>
<span>JAVA_OPTS="-Xmx12288M -Xms12288M -XX:MaxPermSize=1024M -XX:CompileCommand=exclude,net<wbr>/sf/saxon/event/ReceivingConte<wbr>ntHandler.startEvent"</span><br>
<span>3) Enable Native JAI and Native JAI ImageIO</span><br>
<span>4) Enable Tile caching into External PostgreSQL database</span><br>
<br>
<span>Additionally, we have tried the following:</span><br>
<span>1) In /etc/tomcat7/server.xml added maxThreads="50":</span><br>
<span> </span><br>
<span> <Connector port="8080" protocol="HTTP/1.1"</span><br>
<span> connectionTimeout="20000"</span><br>
<span> URIEncoding="UTF-8"</span><br>
<span> redirectPort="8443" maxThreads="50"/></span><br>
<span>2) In /etc/apache2/mods-enabled/mpm_<wbr>event.conf</span><br>
<br>
<span>try to change conf parameters with no results:</span><br>
<span><IfModule mpm_event_module></span><br>
<span> StartServers <wbr> 2</span><br>
<span> MinSpareThreads 25</span><br>
<span> MaxSpareThreads 75</span><br>
<span> ThreadLimit <wbr> 64</span><br>
<span> ThreadsPerChild 25</span><br>
<span> MaxRequestWorkers 150</span><br>
<span> MaxConnectionsPerChild 0</span><br>
<span></IfModule></span><br>
<br>
<span>Still, when 4-5 clients try to render maps, performance radically decrease and geonode become unresponsive.</span><br>
<span>Do you have any idea how to increse performance ?</span><br>
<span>Best regards,</span><br>
<span>Ana Boljevic</span><br>

<pre>Dear Geonode Community,
We have installed fresh Geonode v2.6.2 on Ubuntu Server 16.04. In order to speed up system, we gave Geonode 24GB of RAM and 12 CPU. Unfortulnally, performance are still poor. Apart from basic installation (standard, not developement deployment) we have done:
1) Replace OpenJVM with OracleJVM (see attachment geoserver.png)
2) We've increased the JVM memory by adding into /etc/default/tomcat7
JAVA_OPTS="-Djava.awt.headless<wbr>=true -Xms6144m -Xmx6144m -XX:+UseParallelOldGC -XX:+UseParallelGC -XX:NewRatio=2 -XX:+AggressiveOpts -Xrs -XX:PerfDataSamplingInterval=5<wbr>00 -XX:MaxPermSize=512m"
3) Enable Native JAI and Native JAI ImageIO
4) Enable Tile caching into External PostgreSQL database
For some reason, Server is not consuming memory no mater how many clients are requesting maps. There is always more than 16GB free memory (attachment free.jpg).
If you can give as any hint, idea or help, we would be thankful.
Regards,
Ana Boljevic
