30 secs delay sounds very much like the usual authentication lookup
via identd, although I don't like to comment on your example #1
right now. But try the following:
In /etc/xinet.d/ipop3, /etc/xinet.d/telnet, and /etc/xinet.d/wu-ftpd,
take out the "USERID" option from log_on_success and log_on_failure.
Then run "service xinetd reload" and see whether those delays are gone.
