I am not near the hardware at the moment, so some of this is from
memory. The NAS box is running NAS4Free v188.8.131.52. The hardware is a
MiniITX board (dual core Atom) 4GB memory, Intel board if I remember
correctly. Drives are Seagate 500GBs. I can't send the outputs as I
can't get into the box right now :-) The switch is a ProCurve SOHO, 12
ports. Linux box is a Dell Optiplex i3 something or other, Fedora 18. I
think it was a Broadcom chip. Again, I'll get those stats tonight when I
get back home. I sort of doubt its a network/hardware issue as I can get
the throughput on the same hardware just mounting via CIFS/SMB rather
than NFS. I won't rule it out as I really have no good ideas.
Some results of messing around last night you can see the NFS throughput
is horrible on writes, but good on reads. CIFS is good on both.
I'll check the async status also when I get home tonight. And run some
