It always seems like my transfer speeds are slow, I usually get 2-4mb/s when I transfer files from my window machine and when I try to backup my Mac it takes ~20 hours even though the disk is not that large. I have tried to use both OMV 4/5 on an old laptop but I never seem to get more than 4mb/s. Now I tried to use a Raspberry PI 4, 4gb. Which have usb 3.0 & 1gb lan so that should not be a bottleneck?
I have tried a few different ports & cables on my router but still the same result.
