SABnzbd Forums

Hi everyone. I have a Synology DS1513+, first on DSM 6.2 and now on DSM 7.0.

On the 6.2 version I tried installing SABNZB but the download speed would not come above 11MB/s. Now on 7.0 using docker I get max 23MB/s. I have 1GB fibre internet. NZBGET gets up to 80MB/s but I like SABNZB better.

The NAS has 4GB of memory which fills up pretty fast but even when the memory is only 5% the download does not go any faster.. CPU usage is about 34%.

Anyone has any idea how to get my full download speed?
On the external pc my download speed is maximum (around 90MB/s) but its easier to download straight on the nas..

Hope someone can help me out!

When you use the SynoCommunity package, what speed do you get?
Do you use ssl?
Try more or less connections.

Seems to be fixed, The ssl was the source of the trouble. Now downloading at 100.9MB/s. Not very stable tho, Shoots up and down between 100MB/s and 80MB/s. Don't know why that is but okay

I think you'll get more stable speeds if you limit the speed to for example 90MB/s. It seems at 100MB/s it just can't really keep up and needs to pause the download for a few seconds to clear the buffers.
By matching the maximum speed of your hardware, the buffers stay empty and no pausing is needed.

The SSL impact is a "bug" in Python causing lots of overhead when processing SSL requests.. Hopefully at some point somebody will fix it:

Thanks, will try to set speed at 90 and see what it does

Worked, Tried playing wit that a bit. 97MB/s is the max, if I go higher it goes down but now it stays stable Thanks for that.

Great
