Could you try running the measure_get shell function I included in the
following email?
https://lists.gnu.org/archive/html/guix-devel/2018-12/msg00192.html
For convenience, here is the definition:
--8<---------------cut here---------------start------------->8---
measure_get () {
curl -L \
-o /dev/null \
-w "url_effective: %{url_effective}\\n\
http_code: %{http_code}\\n\
num_connects: %{num_connects}\\n\
num_redirects: %{num_redirects}\\n\
remote_ip: %{remote_ip}\\n\
remote_port: %{remote_port}\\n\
size_download: %{size_download} B\\n\
speed_download: %{speed_download} B/s\\n\
time_appconnect: %{time_appconnect} s\\n\
time_connect: %{time_connect} s\\n\
time_namelookup: %{time_namelookup} s\\n\
time_pretransfer: %{time_pretransfer} s\\n\
time_redirect: %{time_redirect} s\\n\
time_starttransfer: %{time_starttransfer} s\\n\
time_total: %{time_total} s\\n" \
"$1"
}
--8<---------------cut here---------------end--------------->8---
Specifically, I am curious to know what performance you get when you run
measure_get https://berlin-mirror.marusich.info/nar/gzip/1bq783rbkzv9z9zdhivbvfzhsz2s5yac-linux-libre-4.19
from a computer in China. Please be sure to run it two times in a row,
to ensure that CloudFront has cached the object.
CloudFront has edge locations in Hong Kong, so I am curious to know what
performance improvement, if any, you observe.
