So the best speed is equivalent to 42MB/s. Can't tell from this what the limiting factor is (might be the disks). It would be interesting to try putting a buffer (5 x 42MB = 210MB initial stab) at the recv side and see if you get any improvement. -- Andrew _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
