How do you know the delay isn't in the client's lookup of the server?
I concur with Doug's suggestion that you need to trace the connection
process to find out what's slow. Personally I'd try strace (or local
equivalent) first; the odds are that you can spot the issue at the
kernel-call level. You'd probably need to trace both the client and
server sides of the operation.
