Low Upload Speed On Hetzner Dedicated Server

Hello, any reason why I have low upload speed on my server? I tried stopping the haproxy to prevent uploading requests and rerunning the speedtest, still nothing has changed.

  • Please provide traceroute and iperf tests to the target.

  • 4.17 mbit/s is the speedtest.net problem. the script is broken.

    It is very likely an issue with speedtest on some Linux kernels. Try iperf as suggested above.

    Is it the case for just this host, or are you having the same issue when testing others as well?

    when I tested with another machine of mine (who is in hetzner); it shows me a good upload connection speed

  • Send iperf test results to herzner support. they are fast to respond to such issue.

    Thanked by 1Hetzner_OL
  • Do you use BBR?

  • Try this:
    wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py ; chmod +x speedtest-cli ; ./speedtest-cli --share

    Or alternatively, try:
    apt install iperf -y && iperf -c cloudflare.com -p 443 -P 10

  • SpeedBusSpeedBus Member, Host Rep

    It's a bug in the speedtest-cli script when you use it with BBR, another user reported the same issue on Github with the very same speed (4.17 Mbit/s)

    I think it's BBR and not speedtest bug
