Check for any IDENT and/or DNS queries, typically fired off for logging
purposes whenever starting a new connection. The 15 second delay makes
me think ident is the cuplrit. Note that ident queries can be blocked
at either end by a firewall, so make sure you check both ends of the link.
Most services (and service spawners, like xinetd) have flags to
enable/disable logging remote IP, Ident, DNS lookup, etc on connection
startup. Make sure only what you want is enabled for fastest response
times.
