[zfs-discuss] Re: Rsync update to ZFS server over SSH faster than over NFS?

Try mounting the other way, so you read form NFS and write to ZFS (~DAS). That should perform significantly better. NFS write is slow (compared to read) because of syncronous ack. If you for some reason cant mount the other way, then you may want to play with NFS mount-options for write-buffer
