Can you give me the average ping time between you'r client and NFS server ? Regards.

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 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
