<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>

<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
