I've got a bunch of devices at home connected to a Fast Ethernet switch.
  Among them are a Netgear switch (aku), my Linux desktop (haggis) and
my wife's Linux desktop (peanutbutter). So, I should get a theoretical
max of 12MBps in half-duplex mode and 25MBps in full-duplex mode.

That's presumably why internet speed tests on both haggis and
peanutbutter show peaks up to 24MBps (close enough to my paid-for max of

Why, then, do xfers (NFS, scp & plain old ftp) between haggis and
peanutbutter max out just under 12MBps?
