Can you post a tcpdump of a successful connection with delayed_ack
disabled and then the same attempted (unsuccessful) connection with
delayed_ack reenabled? Please use -s 0 (to catch the entire packet) and
use -w to write the binary dump data to a file. That'll allow us to look
at the entire data payload. It's probably best to post those dumps on a
server somewhere and just post the urls to the list.
