even with tuned TCP window sizes, make sure you don't have TCP syncookies enabled on either endpoint.
IIRC Linux (at least) syncookies only come into play when you are being syn-flooded (i.e. when the kernel has to start dropping syns). Having them enabled at other times has no impact, so there's rarely (if ever) a reason to disable them. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
