             Project: JBoss Remoting
          Issue Type: Quality Risk
      Security Level: Public (Everyone can see)
    Affects Versions: 2.5.3 (Flounder) 
            Reporter: Ron Sigal
            Assignee: Ron Sigal
             Fix For: 2.5.3.SP1


>From JBPAPP-4617 "Possible performance issue in Remoting":

JMS remote connections that are used locally result in a lot of calls to InetAddress.getLocalHost() which for some reason is slow. 

Why not:
   private static final InetAddress LOCAL_HOST;

   static
   {
      try
      {
         LOCAL_HOST = InetAddress.getLocalHost();
      }
      catch (UnknownHostException e)
      {
         throw new ExceptionInInitializerError(e);
      }
   }

   private static InetAddress getLocalHost() throws UnknownHostException
   {
      return LOCAL_HOST;
   }

Which is roughly 1000x faster.
