Very low Pystone & Download speed (unraid, docker)

[arsenic0]

So i seem to have a problem others have but nothing seems to be helping

Unraid running Sabnzbd in docker

Gigabit connection, i routinely download off steam at 80MB/s and all speedtests show 1G Up/1G Down.

Intel I7-10700k

32Gb Ram

250Gb m2 SSD Cache drive

I've ensured my Sabnzbd docker is pinned(uses) every CPU core

Direct Unpack is disabled

60 Connections. I can download at full speed on my main PC so i know its not the newsgroup service. I have tweaknews unlimited.

System performance (Pystone) 100788 Intel(R) Core(TM) i7-1070…

Download folder speed 270.6 MB/s (/incomplete-downloads)

Complete folder speed 267.7 MB/s (/downloads)

Internet Bandwidth 73.9 MB/s (591.2 Mbps)


I cannot download faster than 35-40Mb's using the built in 1G download.

From what i can tell my Pystone is VERY low, i've gone in and verified its set to Performance mode in the BIOS so it shouldnt be throttling cpu speed, but im not sure what else is going on.

I get interesting result myself:

SABnzbd (without docker) reports pystone of about 110.000 on my old i3 laptop.
SABnzbd (lscr.io/linuxserver/sabnzbd) in docker on the same hardware reports pystone of ... 9332, 9131, 8591, 37060, 9065, 36523. So between 10% and 35% of setup without docker.

Now the big question: what is the cause:
* the measurement is correct, and docker limits the cpu power available, or
* the measurement / measurement-method is incorrect
* something with the docker image is causing it

I know this is a bit of an older thread but just to address as to why performance may be slower in Docker vs native, seccomp can slow down many processes due to syscall filtering. There is a good article on this if you search on Google for the title of the article:

Code: Select all

"Docker can slow down your code and distort your benchmarks" "pythonspeed"
