SABnzbd Forums

I have been running SABnzb in a VM on my NAS for a couple of years and it has been working great on it with downloads hitting Gigabit speeds. I recently wanted to setup a dedicated system for all the ARR"s + SABnzbd + Plex.

But for the life of me I am unable to get more than 10MB/s download speed from the new setup on SABnzbd. I mirrored all the settings from the previous VM and tripled checked it all. - Speedtes returns back gigabit speeds

When I do the 'Internet Bandwidth'(Sabnzb UI) test on the VM, I get 500Mbps +, but on the new setup it only sees 90Mbps. Dispite the System performance and read/write speed being far better. Actual Speed's from websites and Torrents, on the new machine, I get upwards of 50MB/s (500Mbps)

New Machine is on version 4.0.3, old VM is 3.3.1. That is probably the only main difference

When doing all these test the system is barely under any load (less than 5%). The machines are physically beside each other, connected to the same switch. Doing a test download, the VM hits 50+MB/s and the new machine only sits at 9-10MB/s.

0.46 | 0.49 | 0.40 | V=4200M R=293M System performance (Pystone)
526899 13th Gen Intel(R) Core(TM) i5-13500 AVX2
Download folder speed
1593.8 MB/s /home/user/Downloads/incomplete
Complete folder speed

Any help would be greatly appreciated.

90 Mbps is "Fast Ethernet", not Gigabit Ethernet.

So solve that. Something outside SABnzbd.

That is what Sabnzb(internet Bandwidth test on the UI) is reporting on the new Server, but actual speedtest from fast . com, speedtest . net, and downloading using Transmission (Torrents) all show speeds of greater then 500Mbps (50 MB/s)

Aha. Let's check that we understand eachother:

log in on the Linux system running SABNzbd. Then:

ps -ef | grep -i sabnzbd
to prove sab is running.

then, while SAB is not downloading:

wget -O /dev/null http://cdimage.ubuntu.com/daily-live/cu ... -amd64.iso

and

iperf3 -R -P15 -p 5207 -t3 -4 --format m -c fra.speedtest.clouvider.net | grep receiver | tail -1

and

iperf3 -R -P15 -p 5207 -t3 -4 --format m -c nyc.speedtest.clouvider.net | grep receiver | tail -1


Can you post the output of those commands ... ?

hmm! Well, I guess this concludes it is not a sabnzbd issue

Thanks for helping to point me in the right direction and sorry for the bother.
It's weird that from firefox everything is reporting 500Mbps+

Seems so

You're welcome.
You're the same user as https://www.reddit.com/r/SABnzbd/commen ... the_other/ , right?

Yup, that is me as well.

I have been though all faucets of the internet trying to track down this issue. At this point I am just going to live with it or move it all back back to a low powered VM.
