What does the IPv6 routing table of the system in question say?

 The correct command is ip -6 route.
 You don't have the most basic knowledge and still you feel yourself
qualified to judge about the protocol. That's Dunning-Kruger at work.

I don't have IPv6, I don't have to remember IPv6 related commands.
cer@Laicolasse:~> ip -6 route
fe80::/64 dev wlan0 proto kernel metric 1024 pref medium

And you would not like me using ancient commands.

 

On a slow machine, about a millisecond, yes. That matters in high
performance computing, where professionals do the administration. It
does absolutely not matter on a personal workstation that spends 99 %
of its CPU cycles waiting for keystrokes anyway.

It is the network speed that matters, which is much slower.

 There is zero evidence about IPv6 network speed being slower than IPv4
on a feature-par network.

That is not what happened, and not what I said.

 Of course there are stupid ISPs who that send IPv6 on absurd detours.
Those need to be put out of business.
