    no that is even slower, just rsync over mounted  nfs, a multithreaded rsync does work have better performance.

    Are you doing the rsync over ssh? You might want to look into using HPN-SSH:

    Hi all,
    We have a a few servers  conected via 10g nic  LACP, some of them have  4nic and some have 6nic in a link aggregation mode. We been moving a lot of data around and we are trying to get the maximum performance. I have seen zpool can deliver  2-3GB accumulated  throughput. Iperf does about 600-800MB/sec between those two servers.
    Given  the hardware that we have and the zpool performance,   we expected   to see some serious data transfer rates  however we only see around 200-300MB/sec average  using rsync or copy paste over NFS.  Standard MTU 1500 and nfs block size.  I want to ask the community what to do get some higher throughout and the application level. I hear ZFS send/receive   or ZFS shadow does work faster but it does snapshots. Out data (Terabytes) is constantly evolving   and we prefer something in the nature of rsync  but to utilize the network hardware.

    If Anyone has a hardware setup that can see 1GB/sec  throughput  and does not mind sharing?
    Any software  that  use multithreads  sessions to move data around  zfs friendly? We do not mind getting going with a commercial solution like camvault or veeam if they work.

    Thank you for your time
