Thanks for revisiting this!

Ok, sitting in Portland, Oregon, USA, with native IPv4 and IPv6 over a
wireguard VPN routed via Freemont, California, USA... I tested both IPv4
and IPv6 for those that have IPv6 (US mirror only has IPv4). There is
constant internet activity from other machines on the local network, so
a lot of uncontrolled variables...

The results seem to be all over the place, with the best speed result
france (IPv4), the second best singapore(IPv6), the worst singapore
(IPv4) and second worst the US mirror (IPv4), somewhat surprisingly.

Maybe fetching the same content over IPv4 followed up by IPv6 warmed up
the disk cache on the server side... but clearly not consistently.

My VPN is hosted somewhere with much better internet connectivity, so
maybe wireguard manages to queue packets and send them more efficiently
for the IPv6 connections... sometimes?
