Do you have USER in your log_on_success configuration
in either the default section or that service's
section?  I use xinetd on local address spaces and
have host names in the /etc/hosts file and have no
noticeable delays. The USER logging would try to
connect to identd, which times out at around 10 or 15
seconds.

Also, you can try to add a flags = NOLIBWRAP to see if
your delay is coming from tcp_wrappers which tries to
do a thorough lookup of the connection. If you run
with NOLIBWRAP, make sure only_from is setup or you
will be wide open. The only_from should be just the IP
address in your case.

Also, the latest devel series is somewhat faster in
its address checking. The address being checked was
looked up each iteration through the loop. If
only_from had 3 entries, 2.3.4 & 2.3.5 would look it
up 3 times.
