Download speeds and folder speeds slow in docker

Im running Sab in Docker Desktop on Windows.

Stats in Windows Docker

System performance (Pystone) 408711
Download folder speed 107 MB/s
Complete folder speed 111.6 MB/s
Internet Bandwidth 46.4 MB/s

Stats in native Windows client

System performance (Pystone) 486227
Download folder speed 190.6 MB/s
Complete folder speed 195.4 MB/s
Internet Bandwidth 167.5 MB/s

So you can see that Im only getting about 2/3rds of the disk speed and only 1/4 the download speed I should be getting. The pystone score is a little lower too which is odd.

What gives here? Is this just Docker Desktop being horrible? Is there any way to fix this?

SABnzbd on docker is slower than SABnzbd straight on Linux

SABnzbd on docker on Windows has yet another layer: Linux VM is in between. So indeed slower.

A fix? Run SABnzbd straight on Windows for the best speed.

I was thinking the same thing but Im just shocked Windows Docker is SO slow compared to native.

Ill probably end up just reformatting and installing ubuntu.

Are there slowdowns running in docker on linux? Is this just a Windows issue?

Well I took the morning to make the switch from windows to ubuntu. Im now getting full expected disk speed and internet bandwidth in linux docker.

So I guess windows docker is just a dumpster fire.
