Oh I believe IPv6 is faster but because of completely different reasons.
Modern faster connections more likely have IPv6 while old low-bandwidth 
circuits may provide v4 only.

Some users may also use VPN which is almost always v4 only. Their VPN 
may do funny routing, hair-pinning and similar behavior thus impacting 
their performance.
