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. -- Chris
