Dear Maintainers team,
I've notice that the package download speed (is that the measure?),
seems to have some special edges/cases giving IMHO not realistic values,
see for e.g. the value calculated for 'graphviz' on my current

substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%
I'm not behind a ~ >100MB connection, and it's curious to get 1.15GiB/s
here, is that somehow the value from some cache? or is a spurious
calculation? (IMHO nothing that releases the packaging unusable thus low
priority, just curiosity, is that a bug?)
Thanks in advance,
francisMB

As you can see, the 1.15GiB/s was printed while Guix had downloaded just
5.1% of 1.2 MiB, meaning 61 KiB.
The time it takes to download 61 KiB is very small, which is why you can
end up with surprising values when dividing that by the time it took.
Notice that the final result of 2.2 MiB/s is probably accurate.
There’s not much to do here, except perhaps not displaying anything
until at a bigger chunk of time has elapsed.
