64-bit vs. 32-bit JVM performance

Solution Unverified - Updated -

Issue

  • What are the pros and cons of using a 64-bit JVM versus a 32-bit version ?
  • We would like to know the interoperability between 64 bit java and 32 bit java in terms of jboss EAP. In other words, can we have a jboss instance running 32 bit java interact with another jboss instance running 64 bit java? If yes, what are the details to make this mixed mode scenario work?

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • All Versions
  • Any platform that can run a JVM in both architectures.
