Sabnzbd takes ALL available bandwidth!

[Pate]

And by that, I really mean ALL, so that every other network connection besides sabnzbd first hangs and then disconnects as soon as I start sabnzbd downloading. Not to mention Netflix and such.

This started yesterday, everything worked fine before that. I have made no changes to my configuration.

I am wondering, is this even anything relating to sabnzbd, or is this some misconfigured router between me and the server (Eweka) I am using? Shouldn't all UDP traffic, like Netflix, have higher priority than the TCP traffic that sabnzbd uses?

I guess I could simply limit the sabnzbd bandwidth, but that does not seem like the correct solution.

Anybody have any ideas what might cause this?

Thanks!

Hi and welcome to the forum.

How many server connections have you configured for Eweka?

[Pate]

Hi, and thanks for the welcome!

I have been using 8 connections.

Edit: I dropped that down to 2, and that seems to have helped at least with my browser connections.
Edit2: Even with 2 connections, it still messes up at least Youtube, as Youtube begins lagging and stopping for buffering. And there is no dip in sabnzbd bandwidth usage when I start watching a Youtube video. Before yesterday, sabnzbd bandwidth usage would dip based on other network traffic. Weird.

Has your internet connection slowed-down? Have you run the speed tests in SABnzbd yet?

My internet connection seems to be the same 30Mbit/s as it has ever been. With 8 connections, I get the same 3.0MB/s (max) with sabnzbd as before. When I dropped down to 2 connections, I get 2.6MB/s, so with that it seems to now leave 0.4MB/s for other traffic (like Youtube).

Hmm, I’m out of ideas, I’ll have to leave this one for the gurus.

Big thanks for the help in any case, dropping the number of connections helped with the immediate problem! :-)

I will get new fiber optic internet connection this summer to replace my old ADSL, so this problem might even get solved by that change, if I can't figure it out before that.

Thanks again!

Speed limiting is probably the only effective solution here. The bandwidth provided by your internet provider is so low by todayś standards that it takes very few connections to Usenet to fully saturate the line. Sabnzbd allows for scheduling peed limits too, so you can define certain times of the day as unlimited and only restrict bandwidth at those times you'd typically make use of those other services competing for the same bandwidth.

As for what changed: impossible to tell. Anything that makes sabnzbd compete for bandwidth more effectively, and that includes stuff well outside of your own home such as ISP settings, traffic shaping/throttling, improved infrastructure and peering agreements, etc.
