Another (faster) test from a different machine with Guix System 020184f,
same place and network (60 Mbps):

Thanks for the information, although it looks like you're not well
connected to any of the three machines.

The Singapore mirror is hosted by Vultr, and they do have some locations
closer to you, I'd be interested to see what speeds you get downloading
these files?

https://sao-br-ping.vultr.com/vultr.com.100MB.bin
https://mex-mx-ping.vultr.com/vultr.com.100MB.bin
https://scl-cl-ping.vultr.com/vultr.com.100MB.bin

It feels faster downloading from those locations.



+ Upgraded Guix System to 849286b (May 26, 2023)
+ Moved closer to the WiFi access point (1 m away)

Before starting the tests, I checked the average download speed at the time:

Connection: WiFi
Promoted service speed: 60 Mbps
Reported download speed: 48.8 Mbps
