Remember this is TCP traffic.
RRL is designed to deal with spoofed UDP traffic. It can actually make
non-spoofed floods worse, because RRL pushes UDP traffic to TCP, and TCP
is very easy to saturate.
You might find it helps to avoid truncated responses, e.g. by turning on
the minimal-responses option. (See also minimal-any in BIND 9.11)
