How are you measuring the speed of file transfer? Just one figure at
the end of total data size over time used, or are you looking at it
interactively as the transfer goes along?

If you're doing the latter, and you're not seeing a long period of
0-rate transfer followed by a sudden jump to normal speeds, you do not
have the problem described in that serverfault article.

Really, it does sound to me like the NAS. Does the NAS serve anything,
on any protocol, to any client, above 1.4 MB/sec? Have you checked
the network status lights on the switch and NAS to ensure that you're
seeing a full-speed, full-duplex connection? Have you checked the error
indicators for those ports, if any? I would also try swapping the cable
for a new or known-good one.
