Speedtest against Hetzner servers

README.md

hetz-speedtest

small python for basic speed testing again public hetzner endpoints. provides a rough estimate of latency to datacenters as well.

usage

pipenv install
pipenv shell
python hetz-speedtest.py [lg|md|sm]
# Alternatively
pipenv run python hetz-speedtest.py [lg|md|sm]

Easy terminal version:

for dc in sin nbg1 fsn1 hel1 ash hil; do echo "${dc}: $(ping -i .1 -c 10 -q "${dc}-speed.hetzner.com" | awk -F/ '/^round|^rtt/{print $5}')"; done | sort -n -k2

well that's just latency
