Updated to 3.2.0 from 2.3.6 now only half speed

[fidp]

Hey guys,

Been running sabnzbd on rasp 4 for some time now (2.3.6) and always been downloading fine mostly @ full speed of my connection (500mbit/65MB/s)

Today Ive updated from git to 3.2.0 and removed sabnzbplus and managed to save all settings fine, but no matter what I do now I keep stuck at ~half speed, ie. 25/30MB/s.

Any idea what could cause this, as it seems the hardware, although it being a pie, was able to handle faster speeds?

Tried a couple of different downloads, also Im only using newsgroups.

Thanks in advance guys

That's interesting. Some differences could occur but this sounds like a big difference.

Could you maybe try this: https://sabnzbd.org/wiki/faq#freshstart
And then download the 10GB test-file in the Status and Interface settings window?
Try setting number of connections to maybe 20 or 30 to begin.

Hey safihre,

Thanks for the quick reply man, appreciate it!

I deleted the sabnzbd.ini and bak file from

Code: Select all

/home/pi/.sabnzbd

(after stopping sabnzbd and the [email protected]).
But then, after restarting the service, the web-interface doesn't come up at :8080
I can see in the ../.sabnzbd/ folder that 2 new ini and bak files are created and dont contain my settings .
host and port are

Code: Select all

host = 127.0.0.1
port = 8080

I think this is the last log info from shutdown->delete ini->startup

Code: Select all

You can shutdown SABnzbd and change those lines to be
host=0.0.0.0

This way you can access it remotly again!

[fidp]

Ah ofcourse... Stupid of me.

Got it fired up again, but the results were kind of the same.
I also noticed that last couple of days that the speed has been slightly increasing.
I use usenetserver and never experienced any hiccups from them as far as I can tell, and my network provider has also been very stable.

But, I still think its something not Sabnzbd related, and me changing version was coincidental.

[safihre]

Oke, if it stays this way then let me know. It could be (because we switched Python versions) that it is somewhat slower or faster, but 50% would be a bit too much!

[fidp]

Hmm, I must say speeds going up is not the case anymore.
I rarely hit 40MB/s also with the test files...

Anything I can try to test what's causing it?

[safihre]

It could be the way we changed the caching.
Before we would fill up the memory first, and only wrote to disk later. Now we match the download speed to the write speed of the disk. Especially if you have slower disk, and have direct unpack turned on, this can have a negative impact on speed.
If you open the Status and Interface settings window, and do the disk speed check, what does it show for both the disk speeds?

[fidp]

Its 20MB/s to the temp download folder (toshiba 1TB USB 3.0 HDD)
80 MB/s to the finished download folder (WD MyBook 8TB USB 3.0 HDD)
25 MB/s internet bandwith..? (This ain't right though, it should be arround 65MB/s)

[fidp]

Ill change the download map to the 8TB HDD

[fidp]

To bad results are the same with temp folder changed to the 8TB

And what if you use the internal MMC of your Raspi?

[fidp]

That's pretty weird... That's even less...
I made a new folder in sabnzbd, so rights should be set accordingly.
On the mmc it now says 7,3MB/s on the temp folder

[fidp]

Ok. After downgrading back to 2.3.6 (sabnzbdplus) it went back up to 65MB/s...
Im sorry mate, but I'm sticking to this old version for now, downloads go way faster on the old build.

Thanks for trying to help, if you have more suggestion I'm always willing to try and help out.

Ok. After downgrading back to 2.3.6 (sabnzbdplus) it went back up to 65MB/s...

So, on a Raspi 4 (how much RAM?) you achieve 65 MB/s with SAB 2? That is very impressive.
Is that also for a bigger download, so 1GB and 10GB?

AFAIK, the old SAB 2.x was fast for the first 100MB or so, but then the speed dropped. In my experience SAB 3 achieves better constant speeds.

EDIT: Here is 10GB test NZB: https://www.binsearch.info/?q=reftestnz ... 00&server=
I wonder what speed you get with SAB 2.x
