my CDN measure_get

[zimoun]

Dear,

I do not know if it is useful because it appears to me that providing
CDN service is now on the pipes.

Well, even if I understand all the concerns mitigating the use of
external CDN, I am in favor of this use.
Mainly, because I use guix in scientific context. And it is hard to
explain to my (hypothetical) collaborators that they have to wait.

The figures below are from my laptop connected by Wifi in my
university and then from the cluster head node. I am in Paris.
Note that the default curl version on the cluster is old.


I am not sure to know how to interpret but I see that the CDN seems much faster.


Last, what should be the cost to enable CDN? Any evaluation?


Hope that helps.

All the best,
simon
