Re: [zfs-discuss] Re: Rsync update to ZFS server over SSH faster than over NFS?
Pål Baltzersen wrote: 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 sizes (wsize=) and async (risky but faster!) I guess rsync has a wider ack-window that makes it faster than NFS write (i.e. buffers more without wait-state). Filesizes may have influence on the picture. Could also try NFS over SSH :-) -- Darren J Moffat ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

SSH compresses by default?
