Re: The reason for lack of IPv6 adopton
Hm... faster by design? Or a separate stack which is practically empty all of the time?
The "stack" is conceptional only – you're still moving electrons, photons or radio waves through the same propagator, with the same constraints.
It is certainly possible that a pure IPv6 setup could be faster due to better routing, but I suspect anecdotals comparisons are likely to have other causes.
