Slow Download Speed

[sander]

I'm assuming you use SABnzbd 3.0.0 or 3.0.1. If not, do so.

Then:
Make sure SAB is not downloading.
In SABnzbd's upper right corner, click on the wrench symbol ("Status and interface options"), then click on first tab Status, and there click on the Refresh Circled Arrow. SAB will do some calculations.

What is the result at Internet Bandwidth ?

[sander]

Just keep it here. Nothing secret about the advice I gave you.

OK cool, I am on 3.0.2 and there is no spanner to the top right. There is one on the top left but I don't see the "Status and interface" options Is it different on 3.0.2? Thanks

No wrench/spanner? Oh, are you using the old grey/black/yellow interface called Plush? Then go to http://127.0.0.1:8080/sabnzbd/status/ -> tab Dashboard. Click on "Repeat Test" ... but that does not show the Internet Speed, which we need.

Are you willing and able to switch to new interface called Glitter? If so, you can do that via http://127.0.0.1:8080/sabnzbd/config/general/ -> "Web interface" and in the drop down select "Glitter Default", and then Save Changes. After SAB's restart you should see the Wrench symbol in the upper right corner

(You can always later on switch back to Plush ... but I personally I find Plush old-fashioned)

Done, and it says 3.6MB/s (28.8 Mbps)

OK, good: that is about the Internet speed you told (40 Mbps).

Now we have to find why your News speed is only 600KB/s (which is about 6 Mbps), so only 1/6 of what you should get: which newsserver do you use? How many connections? SSL or no SSL?

And, what are the measurements in the Wrench symobol for:
CPU speed
Disk speed Incomplete & Complete?

[sander]

Yes: In SABnzbd's upper right corner, click on the wrench symbol ("Status and interface options"), then click on first tab Status, and there click on the Refresh arrow, and you get the CPU and disk speeds. Post them here.

[sander]

I think it's best to get an (block?) account at another newsprovider, and test your speed against them. Check out https://www.reddit.com/r/usenet/wiki/pr ... iki_blocks

Can you try this: set each newsserver to 20 connections, and try again.

Worth checking:

As you're connecting from NZ to servers in EU and US: What are your ping times to the newsservers?

Hi Sander, sorry for hijacking this thread.
I have the same issue.
7 days ago my DL speeds suddenly dropped from a constant 22MB/s to a meere 2.4MB/s

Running the wrench test I get 28.4MB/s bandwidth and 43.8MB/s DL folder speed.

This is driving me nuts.

running different types of bandwidth checks I get 256/249Mbps. Im paying for a 250/250Mbps line so thats ok.

Using Torrent it speeds up to max.. but with Sabnzbd I cannot get it to go past 2.4MB/s

Im on Giganews since 2006 and never had any issues before.. not with sabnzbd neither.

Any suggestions?

[sander]

The usual: ISP throttling, router overloading, newsprovider limited, cpu limited, disk speed. You have already ruled out Internet speed and Download folder speed.

[EbolaSmurf]

Using another nzb DLer I get full speed.. nothing has changed on the setup.. that’s why it’s so weird. Only sabnzbd that stopped DL at full speed

Aha! Well, then a possible cause is that you activated the SABnzbd bandwidth limiter. See http://127.0.0.1:8080/sabnzbd/config/ge ... _max_value and upper right corner: the percentage.
