actually, waiting for an ipv6 address would cause a delay if a program
were to sit and wait for a ipv6 DNS address that never comes because the
DNS server providing the service only serves ipv4 addresses.

What I have have seen that causes a problems with some downstream
routers is tcp window scaling and that I've solved by adding to
sysctl.conf...

net.ipv4.tcp_window_scaling = 0
