I have been using FreeBSD 9 with ZFS and NFS to a couple Mac OS X (10.6.8 Snow Leopard) boxes and I get between 40 and 50 MB/sec throughput on a Gigabit ethernet link. Since you have already ruled out the known sync issue with ZFS and no SSD-based write cache, then perhaps you are running into an NFS 3 vs. NFS 4 issue. I am not sure if Mac OS X is using NFS 3 or NFS 4. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
