                 Key: QPID-3706
                 URL: https://issues.apache.org/jira/browse/QPID-3706
             Project: Qpid
          Issue Type: Bug
          Components: Java Client
    Affects Versions: 0.12
         Environment: All Java
            Reporter: Fraser Adams
            Priority: Minor


Connections from JMS take noticeably longer than from C++ 

I know I'm not imagining it because I've just done the following:

long _startTime = System.currentTimeMillis();
System.out.println("Create Connection");
            Context jndi = new InitialContext(props);
            ConnectionFactory connectionFactory =
(ConnectionFactory)jndi.lookup("ConnectionFactory");
            connection = connectionFactory.createConnection();
long elapsed = (long)Math.round(System.currentTimeMillis() - _startTime);
System.out.println("Creating connection took " + elapsed);

And it's consistently telling me it's taking between ~ 920 and 990
milliseconds

So that backs up my gut feeling that "it seems a bit slow"

I moved the "_startTime" bit to just before "connection =
connectionFactory.createConnection();" and it was still registering >
900ms so it looks like the problem is somewhere in createConnection().

Connecting from C++ client using qpid::messaging is extremely quick (it's not noticeable and I suspect is only taking a few milliseconds).
