This does not sound like a problem with the code. A nifty way of troubleshooting an HTTP server is to connect to it to telnet to it on port 80. Then you can type something like:

GET /index.html HTTP/1.1

and observe the server's response. See if you get a delay using this approach.

You may also want to turn off any firewalls to see if they are responsible for the slowdown.

Try replacing 127.0.0.1 for localhost. If that solves the problem, then that is a clue that the FQDN lookup may indeed be the possible cause.
