During last years much attention was paid for process of deploying IPv6 in different regions. And with growing IPv6 adoption the requirements also grew up. Today we require not just working IPv6 but reliable IPv6. Of course this aim brings to our attention IPv6 network latency which we want to be comparable to IPv4 latency. First measurements gave community very interesting and promising results – for some networks IPv6 was faster than IPv4. But why IPv6 had less latency – there was no clear evidence. In my report I’m going to discuss reasons why in some cases IPv6 is faster than IPv4 and why it is slower in other ones. - See more at: https://www.nanog.org/meetings/abstract?id=2591#sthash.aLuWKSDh.dpufTried to understand claims of faster IPv6 performance. Assumed that it must arise from different network paths. Found more paths in v4 vs v6. "Comparing different graphs" (where "graph" means "set of network paths")
Decided to compare connectivity for v6 vs v4 hosts. Found v6 is a subgraph of v4, as expected. Found that most paths going through Hurricane Electric - connectivity of HE is better than anyone else in v6.
Question: Is HE Tier-1? Who is Tier-1? No one will explain who is a member of Tier-1 club.
So comparisons of v6 speed are comparisons of HE performance at this time.
