Even when I use ipv4.menedetter.net and so have my system connect to your's by IPv4, the above code is executed on MY system and it calls ipv6-test.com over IPv6 because my system supports IPv6. And so ipv6-test.com reports that I connect by IPv6.
The button reports how I connect to ipv6-test.com, not how I connect to YOU.

MV>> My provider says I have 50/5
RM> For IPv4 it sounds good. RM> Question is why is IPv6 so much slower.
I don't know. But it is not incidental. The speed varies a bit but the difference between IPv4 and IPv6 is consistent. IPv6 speed is about half of IPv4.
RM> And if the problem is on my side or yours or both ;)
Other dual stack speed tests perforned from here show no consistent sigificant difference between IPv4 and IPv6...
