Hi Meiyo,
Thank you for sharing this information with us!
Can you also share what numbers you get when you run measure_get against
berlin.guixsd.org directly? Clearly, the connection from you to
CloudFront is not as performant as it is for others in other parts of
the world, but I wonder if it's still better than accessing berlin
directly. If you could run measure_get against berlin directly and
share the numbers, we can see if it represents any significant
improvement for you.

Well, that's not great. Perhaps it's still better than it would be if
the DNS name resolved to a location in Europe, though.

I see, this is about 143 Kbps (not Mbps) of throughput, and 347 ms after
DNS name resolution.
