Unless your "small arm linux machine" is a raspberry pi, you are changing
too many variables to make a meaningful comparison.  Benchmarking i/o across
the internet will also introduce enough variation to suggest an experimental
sample size of more than one attempt.

An interesting set of experiments might be to run both linux and plan 9 on
the pi4, try the built-in ether adapter and the usb dongle, and try fetching
both from http:// and https:// (to see how much of the variation is due to
tls decode speed).
