Re: Download slowdowns limited by CPU on fast Linux PC

The disk speed limit starts to pop up in about 5 minutes after the download starts. But first the article cache fills up (my limit is set to 1G). That could be the internal workings of the ssd, something to do with zfs, or the combination of both. Many low end nvme drives (no dram cache with qlc fl...

Re: Download slowdowns limited by CPU on fast Linux PC

I limited the speed to 100 MB/s and no slowdown either: System load 0.94 | 1.09 | 0.61 | V=2566M R=627M The CPU load was slightly higher towards the end. I need to test this with larger/longer downloads. It takes a while for them to start. P.S. Towards the end of unpacking I see this CPU load: Syste...

Re: Download slowdowns limited by CPU on fast Linux PC

Hmm, interesting. I limited the speed to 90 MB/s in SABnzb and there was no slowdown on the 10GB test. At the end the status was: Used cache 51.3 MB (74 articles) System load 0.65 | 0.29 | 0.13 | V=2304M R=366M So, the CPU load didn't rise high and cache load was mostly below 100 MB. What's the reas...

No. I will try that. While on Windows I never had to limit the download speed in SABnzb and it maxed out.

Re: Download slowdowns limited by CPU on fast Linux PC

The slowdowns don't start immediately, it takes a few minutes of steady download at max speed. So, with the 1GB test it's fine, with the 10 one the slowdowns start towards the end. Yesterday I downloaded about 50GB and the slowdowns started as usual, in a couple of minutes, and the saw-tooth-like sp...

Re: Download slowdowns limited by CPU on fast Linux PC

It is my own system. It has a Plex server, Radarr, Sonarr etc. on it. But nothing was actively running at the time when I was doing tests. The load is high from downloading with sabnzbdplus. At idle it looks like this: Used cache 0 B (0 articles) System load 0.02 | 0.15 | 0.17 | V=3368M R=215M Initi...

Download slowdowns limited by CPU on fast Linux PC

I googled and saw many similar posts but the conclusion was that the CPU was too slow. But this is not my case and I haven't seen anything applicable to my case. I installed sabnzbdplus on Ubuntu 22.04.1 LTS via the ppa:jcfp/nobetas repository according to the instructions. I run it as a service. My...
