As the data at http://bgp.he.net/ipv6-progress-report.cgi shows for the
IPv6 and IPv4 nameserver tests, some of the time IPv6 connectivity is
*faster* than IPv4 connectivity (66 out of 264 test cases), because of
network topology differences due to different peering and transit
relationships between IPv4 and IPv6.

Just as a odd data point, I see this for the only IPv6 test-bed I have
available now, including tunnels.

Home DSL (UK) -> EU tunnel broker -> IPv6 cloud -> US tunnel broker ->
hosted server (California) is consistently 10-20ms lower than home -> IPv4
upstream -> IPv4 cloud -> server.
