Hi there,
I recently switched from SabNZBD to NZBGet because I heard that it has much better performance when running on weaker NAS systems. I have NZBGet running now on my Drobo5N and for the most part I am really impressed. Originaly I had SAB on my main PC and would download around 10 MB/s on my 100Mb connection (I often get above my rated speed). When I moved SAB to my Drobo5N though the speed dropped to about half, or 5MB/s. After doing some reading I found that this was due to the performance limitations and that NZBGet was the answer. So I installed NZBGet onto my Drobo and was immediately impressed to see my speeds jump back to 7-9MB/s which was really impressive so Good Job!
However I am noticing one problem. I get great speeds when the articles have full availability on my primary server, Usenetserver. However when NZBGet falls back to one of my two backup servers (Astraweb and Blocknews) the speed plummets down into the 200-700 KB/s range! Pretty much anytime I see "Backup: XX%" in NZBGet, my speed is crap. The thing is though that I don't have this problem in SAB. All three of these servers will be just as fast in that application.
Is there some special handling of backup servers in NZBGet that maybe I need to tweak?
