I= tried to avoid any local slowdowns by doing this with a wired connectio= n at a time when there was little other activity on the machine or the L= AN and downloading to a tmpfs. Anecdotally, the speeds for servers *other* than bordeaux-us-east-mirror= were faster in this trial than feels typical here. The results I report= ed at https://lists.gnu.org/archive/html/guix-devel/2022-07/msg00320.htm= l (e.g. 8.17MB/s for bordeaux.guix.gnu.org) might be more usual. Subject= ively, my impression of the non-mirrored substitute servers is that ofte= n the speeds is ok, but when they are slow it is very, very slow. Philip
