It's not necessarily overhead as in "extra data" but also round trip
delay times.  SMB was designed for use with a low-latency local network
connection, in contrast to FTP which was designed to just stream raw
data over a TCP connection.  In other words there's a bunch of message
passing and other "overhead" that takes TIME in addition to bandwith
with SMB.

I think you'll find that the Cygwin "cp" command takes about the same
time as "copy" from a regular command prompt, which should also be
comparable to Explorer's copy function.
