[GeoNode-users] Poor performance GeoNode

[Ana Boljevic]

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=true -Xms6144m -Xmx6144m -XX:+UseParallelOldGC -XX:+UseParallelGC -XX:NewRatio=2 -XX:+AggressiveOpts -Xrs -XX:PerfDataSamplingInterval=500 -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
