Per item, you have to tell what your setup is, and what you tried to analyze it.

The wrong reporting "Internet Bandbreite 0.6 MB/s 4.8 Mbps" should be solved. Can you try again?

(Details about the server side problem: https://github.com/sabnzbd/sabnzbd/issu ... 2953314498)

(And no, it does solve 45 versus 105 MB/s)

It seems solved (both resported speed and high CPU usage), by changes on sabnzbd.org / cloudflare server side.

Can you check again?

Hmm, 3.13.2 reports a high Internetspeed on Linux, but reports a low Internetspeed on Windows?

See https://github.com/sabnzbd/sabnzbd/issu ... 2942809909

What if you lower number of connections to 1?

So ... is there any downloading from Astraweb going before the 502 error message?

And: if you use the 100MB SABnzbd test download (via the wrench in right upper corner): does it work?

If in SABnzbd you've filled out the credentials for eu.astraweb.com, and you think they are correct, and you still get the error: contact Astraweb. EDIT: Where do you the '502'? Because, when I try to connect to Astraweb with fake credentials, I get "Authentication failed, check username/passwo...

You're on Windows, with pre-built SABnzbd binary?

For example: "Python Version: 3.13.3"

During the test, which process is causing the high CPU usage? Check with Windows / Task Explorer (I don't know the exact name)?

If you turn off your firewall and your virusscanner, and repeat the test: still high CPU usage, and low results?

As long as that's so different, it's hard to say anything useful.

The general info: https://www.reddit.com/r/usenet/comment ... eds_thread

It's all very weird: things don't match: - 45 MB/s newsgroup downloads - Internet Bandbreite 0.85 MB/s 6.8 Mbps (which is just a HTTP download) - speedtest full performance 850-915 Mbit ... all on the same computer. Do you have another computer on your LAN on which you can do the same tests? And you...

Is that on the same machine as SABnzbd is running on?

> Internet Bandbreite 0.85 MB/s 6.8 Mbps

That is very low.
Did you test while SABnzbd was not doing anything? Because you should
