I will definitely try, but I think it's the ethernet nic driver which needs a boost. Although what I can imagine is that hdd in pio mode terribly slows down the nic.

A while ago I did some measurements:
- Raw write speed to HDD is ~4.5mB/s and read speed ~9.5mB/s (measured by dd from and to /dev/zero)
- The NFS read/write speeds are ~2mB/s (direct 100mbs full duplux connect).

From this I more or less concluded that it is the nic driver to blame but who knows.

Improving performance is high up on my priority list and I will start work as soon as samba 3.0.7 is running stable on the wl-hdd.
