Low download Performance with SABNzbd+

[citizengray]

I have fairly recently setup a new unraid machine.

 

I have installed SABnzbd with CA following the commonly available tutorials.

 

I am very concerned with the performance of SABNzb downloading speed.

I get about ~25MB in peak performance, but most of the time I get ~6-7MB.

 

Of course you might think it's my broadband that is limiting... but I have 1gbs. And I run tests from my macbook using Binreader, form the same Newsgroups servers and I get consistently ~60-80MB/s there.

 

The specs of my unraid machine should be largely enough:

- AMD Ryzen 5 5600G

- Raid 1 Cache drive (where all the docker images run and download to)  nvme 1tb x 2

- 10GBs NIC card - Cat7 cabled (sustained local transfers speed are ~120MB/s)

 

I have also looked into configuring SABnzbd optimally, like lowering the SSL Cypher etc. But nothing seems to work.

 

How do I go about debugging this ?

Try increasing number of connections? Also check if there's another port you can use.

Ah... the port did it... weird... went from 443 to 5543 why !? I know get ~75MB/S peak.

Thx for the tip.

While we are talking about SAB, I have another issue.

 

The working folder __ADMIN__ has a different set of permission than the other files in the incomplete folder (700 vs 744) and it seems that SAB cannot delete that folder and therefore leaves a a whole bunch of folder being after failed jobs... any ideas ?

To be fair I have the exact same issue. Just upgraded to 1gb in UK and doesn't download faster than 50MB/s but honestly most of my downloads are automated these days.
