I installed unRaid yesterday, and despite its very nice features, it is extremely slow when compared both with Proxmox and TrueNAS on the exact same system.
I am copying my files from another drive, mounted on unRaid, where I have the backup from my old install, to my unRaid array with rsync, and I am getting speeds of 50 MB/s
Results with XFS and BTRFS are mostly the same (I reformatted my array to see if that was the problem).
Parity drive is deactivated
Speeds both on Proxmox and TrueNAS (only with 2 cores active) for the same system, where between 150 to 180 MB/s
As you can see, DiskTest results done on UnRAID show a top speed between 200 MB/s to 100 MB/s
So, what is going on here? Disks seem to read just fine, so why it's so slow to copy data between disks on UnRaid when it's not with other OSs?
