Hi,
yes it was SMB, running on a windows Server as client, i.e. mount share via Samba, run on client box.
I see I said 5122, can't remember the exact setup, maybe this was after switching to the other board. Will need to see if I find some old notes.
Its likely that some of the performance was from memory, but I used a 100G test file size, so hopefully that excluded most of it; but in the end it shows what FreeNas can do with good hardware (and rdma), how many drives of what type/setup will depend on specific requirements.
Re 53Gbps - thats what I think (remember) was the maximum I hit in various experiments, and it either was with the same 12 drives or a mirror'ed optane setup, didnt have anything else at that time.
Combining both would not speed up things.
