Hello,
Since a couple of days, it seems that nzbhydra2 is quite slow.
So my first thought was to try a speed test from the docker.
I ended doing a speed test on lsiobase/ubuntu:bionic (base for nzbhydra2)
Testing upload speed
Upload: 3.45 Mbit/s
And from the host:
Upload: 21.19 Mbit/s
I tried on a fresh docker on the same server and also a raspi3 and got the same results.
I even tried from https://labs.play-with-docker.com/ :
Testing download speed................................................................................
Download: 657.60 Mbit/s
Testing upload speed......................................................................................................
Upload: 4.14 Mbit/s
Here are the commands I ran.
Host:
docker run -it --rm --name=slowspeed lsiobase/ubuntu:bionic bash
Docker:
apt-get update ; apt-get -y install speedtest-cli
speedtest
Have a nice day
