40MB/s

Is this writing to parity array?

i've disabled parity drive because i'm doing a big transfer data 6tb.

This suggests the problem might well be network related and nothing to do with SMB.

I've tied pluging the ethenet cable into the other port on the motherboard but it has not made any difference. I did notice unraid was showing the same mac address.
