Glassfish Application Server Performance tunings

If you want to improve performance of your application running on Glassfish application server, you can try out following JVM options. We got significant performance improvement by using them.

<jvm-options>-server</jvm-options>

<jvm-options>-Xms3000m</jvm-options>
<jvm-options>-Xmx3000m</jvm-options>
<jvm-options>-XX:MaxPermSize=192m</jvm-options>
<jvm-options>-XX:NewRation=2</jvm-options>
<jvm-options>-XX:+AggressiveHeap</jvm-options>
<jvm-options>-XX:+AggressiveOpts</jvm-options>
<jvm-options>-XX:+UseParallelGC</jvm-options>
<jvm-options>-XX:+UseParallelOldGC</jvm-options>
<jvm-options>-XX:ParallelGCThreads=5</jvm-options>

By using these performance tunings, we are able to get almost 30% more TPS (Transactions per Seconds).If I can be helpful, please do let me know. I have spent enough time on Glassfish and OpenESB performance tunings.
