Hello @LittleLama... The problem was a bad nvme drive...while the drive worked somewhat it had slowed down to a crawl...I RMA'd the drive and replaced it and afterwards everything worked fine.

I also used SanDisk SDDR-B531-GN6NN micro SD reader with a SanDisk 32GB High Endurance microSD card. Downloaded the flash backup zip from the Unraid UI and used the Unraid installation/creation tool from the website to install the zip. Transferred my license from old USB Flash drive and everything is up and running.

So after some more testing I found out that my nvme drive was acting up. I would sometime benchmark fine at other times it has atrocious speeds, down to 40mb/s. I had backed up the cache drive and reformatted it from btrfs-encryted to xfs-encrypted. Still had the problems after I moved everything over. I decided to replace that drive with a sata SSD and since the performance of both dockers and vm's is back to normal. Smart data doesn't show any problems for the nvme drive. The weird part is that I tested the drive once again in the unassigned devices and it performed beautifully.
Question is the drive bad (as in hardware?) or was it something to do with its place as cache drive and unraid?
How do you verify that the hardware nvme is bad besides smart data and simple benchmark?
Drive Benchmark is attached.

I put this in general because i seem to have 2 issues but i believe they are all related to linux.
Basic Idea:
Docker pull and install are slow, performance is bad.
Linux VM took 40min to install 110 mb update.
Long Version:
I had noticed that the docker containers performed slowly. The navigation on Nextcloud being slow was the first thing that showed up. I the issue cam back up when i installed the binhex Minecraft docker container. downloading and extracting seems to be slow as the docker container was pulled down. After installation the server Minecraft docker crashed when i had 3 player. I installed binhex's MineOS and similar problems took longer than usual to pull the container and extract.
I deleted the docker image and reinstalled docker containers. Things still seems to be slow while pulling and extracting. Minecraft dockers still crashed.
Next I installed the server on a windows 10 vm and that seemed to work better and not crash.
I then installed the MineOS Turnkey as a vm which is based on Debian. Still had bad performance issues and crashed.
I then installed Ubuntu server 20.04 (8bg mem and 4 core 8 threads) as a vm, sent the sudo apt update and upgrade comands and it took over 40 min to download 110 Mb and install them, which in my opinion is slow.
Unraid Server:
Ryzen 2700 with Asus x370 prime pro and 32 GB ECC ddr4.
8 disk array with 1 tb HP ex920 nvme SSD as cache
All vms and docker are assigned to cache or set as prefer cache.
Dockers that are always running: Plex, Nextcloud, mariadb, OpenVPN, qbittorent
VM's: 2 Windows 10 (1 gpu passthrough, one on VNC), 1 Unbuntu server 20.04, Mac High Sierra.... all Vms rarely run, and one at a time.
Diag zip attached.
Thank You

I too thought that it could be a btrfs problem. I formated the drive in windows and still had a problem with it. The next SSD installed I used xfs and had no problems since.
