Ben,
The settings for -XX:PermSize=512m -XX:MaxPermSize=512m seem a bit large based
on the max heap size of 1024. Did you run some tuning tests to see that these
sizes were needed? I usually see settings on high load servers around 128/192
up-to 192/256. These are all based on the particular app and server in
question. Your results may vary depending on the server and application needs.
Also, there are other settings you should add. The GC setting is good. Parallel
GC is meant for multiple CPU servers. However, the default execution times of
the GC is every minute unless you set them. Use these settings
(-Dsun.rmi.dgc.client.gcInterval=600000 -Dsun.rmi.dgc.server.gcInterval=600000
) to set the time interval in millie seconds. I've found tens minutes is a good
place to start then monitor your app and server and adjust accordingly.
Also look at setting the ratio of perm to new gen -XX:NewRatio=3 .
Hope this helps you in the right direction.
