The traditional reason for this is that there is no reverse
lookup (PTR entry) for your address in the DNS.
The server tries to look up your address, to find your hostname
(such as for the log), and waits for the DNS reply. When the DNS
times out, then it does something else (like put in the IP address),
and that is your delay.
