Yeah, Geoserver itself isn't using that much memory, the boxes just have a
ridiculous amount of RAM. There are some other apps running in the container as
well (e.g. Solr and some other apps).

Hi Oliver,
I'm running both, but it did require updating the JAVA_OPTS for Tomcat. I've
got a lot of RAM, but here's the config I'm using:
JAVA_OPTS="-server -Djava.awt.headless=true -Xms20G -Xmx20G -Xrs
-XX:PerfDataSamplingInterval=500 -XX:MaxPermSize=512m -XX:PermSize=256m
-XX:+UseParallelGC -XX:SoftRefLRUPolicyMSPerMB=36000 -XX:+UseParallelGC
-XX:+UseParallelOldGC -XX:+AggressiveOpts -XX:NewRatio=2"
20GB? GeoServer is probably not going to use 1/10th of that, even under load,
as its architecture
it strongly data streaming oriented (meaning, it never tries to load all the
data it needs in a single
shot, it gets it in small bits instead).
But maybe GeoNetwork benefits from having that much memory for its Lucene
indexes?
Cheers
Andrea
