Re: Why is IPv6 faster?
IPv6 isn't faster, unless it has a lower RTT path than IPv4. As ISPs make their IPv4 & IPv6 peerings congruent and dual-stack CDNs the relative performance of IPv6 will continue to improve. Eventually ISPs and CDNs will put less effort into maintaining the IPv4 peerings and distribution of IPv4 enabled CDNs. Then the performance benefit that IPv4 enjoyed up until a few years ago will change in IPv6's favour. It is already happening from some operators to sites like Facebook.
