I can't get performance like this with any public speed test I've tried, so I wrote my own.

This script fetches and caches a list of public iperf3 servers provided by the public-iperf3-servers project.

Usage: ./speedtest.py [command]
    refresh: refresh server list from web source
    run: run download + upload test
    bench [n]: benchmark closest n servers for best download speed

• refresh downloads the server list and determines which servers are accessible (and how close they are) based on ping

• bench attempts a download test on the n closest servers (using the cached ping value, see above), and ranks them based on their performance.

• run performs both download and upload tests with the best server, as determined by previous runs of bench.
