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).
