JVM tuning with Seam and JBDS

[gonorrhea]

what is the recommended min/max JVM tuning settings when running Sun 1.5 JDK with JBDS 2.0 and Seam 2.x?

need to know for Eclipse and JBoss JVMs (both plz)?

3 GB Windows OS...

Ok, here's what I have right now as VM args in my JBoss edit config:

-server
-Xms256m 
-Xmx1024m 
-Dsun.rmi.dgc.client.gcInterval=3600000 
-Dsun.rmi.dgc.server.gcInterval=3600000 
-XX:+UseConcMarkSweepGC 
-XX:+CMSPermGenSweepingEnabled 
-XX:+CMSClassUnloadingEnabled 
-XX:MaxPermSize=512m 
-Xverify:none

this is based on recommendation in DAllen's book                     

and this is from my eclipse.ini:

-framework
plugins\org.eclipse.osgi_3.4.3.R34x_v20081215-1030.jar
-vmargs
-Xms512m
-Xmx512m
-XX:MaxPermSize=256m
-Dosgi.bundles=reference:file:org.eclipse.equinox.simpleconfigurator_1.0.0.v20080604.jar@1:start,org.eclipse.equinox.transforms.xslt@1:start,org.jboss.tools.equinox.transforms.xslt@1:start

My developement environment, I starts my JBoss5.0.0 server from Eclipse3.4.1 on WindowXP-4GBRAM

(1) Eclipse shortcut
C:\java\eclipse3.4.1\eclipse.exe -clean -Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m

(2) eclipse.ini
--launcher.XXMaxPermSize
256M
-framework
plugins\org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m

(3) Eclipse-->JBoss server-->Edit launch configuration
Program argument: -c default -b 0.0.0.0
VM argument: -Dprogram.name=run.bat -Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m
(As suggested in Seam Reference 2.1.1GA.pdf Chapter2.1)
