I had to rebuild my OMV NAS and while doing that - I re-initiated the storage as ZFS. I re-created all my old SMB shares and am in the process of copying everything back over from a Nas4Free box (I use 2 different installs for testing). I use Allway Sync to copy from the Nas4Free to OMV using mapped drive letters from a windows 10 box.
The process is painfully slow. My wife wrote a book on wildflowers and has 363,623 pictures (mostly .jpg, some raw) and it takes about a minute to copy 3-4 pictures over. - at this rate it is going to take forever..
I have both boxes connected to a 1-Gig switch
Any thoughts as to why it is so slow (I did read the SMB thread about tuning - but it did not help)
TIA
