Do you have a firewall blocking access to port 523? It looks like Control
Center first tries to connect to this port, and only later goes to the port
the instance is listening on. So if port 523 is blocked you have a delay
(though not 4 or 5 minutes, in my experience.)

Based on your comment that you have the same issue with a Linux DB2 Client
other than CC makes me think this is *not* the issue, but I just thought I'd
put it out there.
