[jboss-user] [Performance Tuning] - JBoss AS Performance (with EJB 3.0)

[grdzeli_kaci]

hi all,
i have topic about this on this forum
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=106866

i want performance tuning of jboss application server and my ejb 3.0 project,
there i post my server parameters
anonymous wrote : 
  | 1.AS - JBoss Application Server 4.0.4GA
  | 2.Database - Oracle 10G 10.2.0.1
  | 3.EJB - 3.0 Framework
  | 4.OS - SunOS 5.10
  | 5.Sun Server - Memory: 16G phys mem, 31G swap, 4 CPU, 
  | 

also i have java performance configuration :

  | JAVA_OPTS="-server -Xmx3168m -Xms2144m -Xmn1g -Xss256k -d64 -XX:PermSize=128m -XX:MaxPermSize=256m
  |    -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000
  |     -XX:ParallelGCThreads=20 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
  |     -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=31 -XX:+AggressiveOpts
  |     -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -XX:+PrintTenuringDistribution
  |     -Xloggc:/export/home/jboss/jboss-4.0.4.GA/server/all/log/gc.log"
  | 

maybe i have something incorrect to achieve best performance can anybody help me ?

if JBoss Application Server could persist 1500 - 2000 entities per second, it will be great,
i have mission critical task, on development time i could not define all business requests for my program, already i wrote so large many application using distributed databases and applications, now i have very bad problem - performance.

and also, we (my company and i, i am a developer for this company) are trying to bye JBoss Application Server support "JBoss Enterprise Middleware Subscriptions" but yet we need to  assure that we could resolve this problem,

is it possible to resolve this problem? 
maybe we could change some configurations for best performance ?
or maybe Is it necessary to bye support to resolve this problem ?
