[GeoNode-users] Poor performance GeoNode

Fri Sep 8 00:11:46 PDT 2017

Hi Alessio,

Please receive screen video recording link, so you can see by yourself what do we mean by "Poor Performance".
https://www.dropbox.com/s/2ai2n8764p1ny9n/2017-09-08-08-38-33.flv?dl=0
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).
Please reveive one typical kml layer in the attachment.

Regards,

Ana Boljevic

Can you please better explain what you mean with "Map Performance" exactly?

Getting the list of layers or rendering the map?

Also, how many layers you have and which type (vectorial / raster) ?

Are you able to identify performance issues? Those are on GeoNode or GeoServer?

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.

Alessio Fabiani

Hi Angelos and John,
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:
1) Replace OpenJVM with OracleJVM
2) We've increased the JVM memory by adding into /etc/default/tomcat7
JAVA_OPTS="-Xmx12288M -Xms12288M -XX:MaxPermSize=1024M -XX:CompileCommand=exclude,net/sf/saxon/event/ReceivingContentHandler.startEvent"
3) Enable Native JAI and Native JAI ImageIO
4) Enable Tile caching into External PostgreSQL database

Additionally, we have tried the following:
1) In /etc/tomcat7/server.xml added maxThreads="50":

  <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               redirectPort="8443" maxThreads="50"/>
2) In /etc/apache2/mods-enabled/mpm_event.conf

try to change conf parameters with no results:
<IfModule mpm_event_module>
        StartServers                     2
        MinSpareThreads          25
        MaxSpareThreads          75
        ThreadLimit                      64
        ThreadsPerChild          25
        MaxRequestWorkers         150
        MaxConnectionsPerChild   0
</IfModule>

Still, when 4-5 clients try to render maps, performance radically decrease and geonode become unresponsive.
Do you have any idea how to increse performance ?
Best regards,
Ana Boljevic

apache2 mod_wsgi needs tuning. Add workers and up memory limits per worker

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
