I often find that going to the command line on Mac OS X is very
helpful, but since the GUI really is very well done for most (but certainly not
all) tasks, I usually don't remember to go to the command line until after I
have been beating my head against the GUI for too long :
d 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 NF
writes since I did the destroy
then I *might* have a chance at this ... HELP!
