Last time I checked that, I never got the object from SWH because a bug
on their side. Nice now they cook the content.
Note that SWH is an archive and so it is expected to take a long time to
extract a large dataset as the files of the Guix repository is. Many
data are stored cold not to say frozen and that’s why it takes a long
time to warm them up.

Well, if I understand correctly, SWH cooked the full Git repository of
Guix and somehow it is probably too big. Hum, I do not know how to
investigate…
Thanks for the report!
