I do not believe I have compression enabled am I mistaken? isn'y SATA2 300MB/s? and I am doing ~6MB/s per disk? I built this machine with 4GB of memory because I thought ZFS would like it. now maybe a re(4) interface isnt the best choice. if that is the problem here I can change it. We spent ~$800 on a hardware RAID card thinking that it would help performance Why is it that with sftp we do not see the pauses in Network transfer? # iostat -zxC 1 (with NFS and ZFS) extended device
