You could try adding some log() lines to nntpservice.js to find out if it's event executing immediately upon connect?

If it's not, enabling debug-level log output for the services server and pasting that log output here would be helpful. e.g.

  4/15  12:05:58p  7608 NNTP connection accepted from: 71.95.196.36 port 55342
  4/15  12:05:58p  7608 NNTP JavaScript service thread started
  4/15  12:06:03p  7608 NNTP Hostname: synchro.net [71.95.196.36]
  4/15  12:06:04p  7608 NNTP Logging in Guest

That 5 second delay there between "JavaScript service thread started" and reporting the hostname (of the client) is likely just the DNS name resolution. That's followed by ip*.can and host.can filter file checking. And then of course, if there's been any failed login attempts from the client IP, that could invoke some throttling (delays). So there are a lot of opportunities for delay in this process and the log output should provide you the clues you need to find out what those are in your case.
