Even more slow transfers on Synology ...

[jumbum1]

I'm trying to set up my new Synology DS1621+ with SABnzbd, previously using a DS418j, which gave me around 20 MB/s ... On that unit, I should have had higher speeds, but it said Internet Bandwidth was around 20MB/s, with 20 connections from Newshosting (my only Usenet provider currently).
I gathered that the slow speed was maybe due to the inherent limitations of the ARM cpu, when using SSL ...

Now I'm getting pretty much the same reading on the new and much faster 1621+, which puzzles me ...
I tried running openspeedtest directly on the NAS (1Gbe), which gave me a good 700 mbps internet speed, which translates to almost 90MB/s ... So why am I only getting 25MB/s at best?

Tried AES128 cipher and 100 connections from Newshosting (max) ...
Any ideas?

SAB in docker, or straight on Synology OS?

Oh, sorry ... the latest SynoCommunity installer in DSM 7.2.
I'm no good with Docker/Container Manager, not yet anyway ...

I don't understand what you say.

I installed straight on Synology OS

Clear.

Why not more than "20 connections from Newshosting"?

If you run SABnzbd on your PC/Mac/Linux, with the same settings, what speed do you get for the 1GB Test Download?

Problem solved :-) I'm sorry to have bothered you guys, but sometimes it's the input from others, that get you on the right track ... Thank you for that
My Synology DS1621+ is now downloading steadily with 100 connections at around 100 MB/s, my old DS418j around 50 MB/s.
So, the whole thing seems to have been a problem right from the start (we're talking a couple of years), without me even knowing it; the stupidest thing = QoS (Quality Of Service) in my router, which had kind of gradually (and randomly) stacked up some kind of prioritization of internet bandwidth for all units on my network.The second I deleted all of those from the list, the download speed smacked through the ceiling :-D
Hope this can help others!

I QoS

... not.
