I tried some file serving with net6501-70. I used freebsd 9 and zfs. Used cryptography, and was writing at 2~3MB/s. Raw zfs tops at around 12MB/s. When I used similar clocked atom from intel motherboard, this jumped to 27MB/s. Then I remembered some email from Soren, about some busses limits on it, and all got clear. I was using a esata 6Gb/s pcie card.
