[Nottingham] Network speed test

[Rory Holland]

I think the protocol with the least overhead would be to pipe a file of
known size over netcat, and time how long it takes.

On one machine, run:

nc -v -l 2222 > /dev/null

(Make sure you’re not blocking connections to 2222!)

On a second machine, run:

dd if=/dev/zero bs=1024K count=512 | nc -v $IP_OF_FIRST_MACHINE 2222
 dd will give you your speed:

536870912 bytes (537 MB) copied, 4.87526 s, 117 MB/s

The above from here:
