You definately want to comment out at least net.inet.tcp.delayed_ack=0

Try temporarily setting net.inet.tcp.sendbuf_auto=0 and
net.inet.tcp.recvbuf_auto=0 and see if that changes anything.

I've seen strange issues with IPv6 and the automatic buffer sizing,
perhaps you're somehow running into the same thing with IPv4.
