Except that he said "I can copy files between the Win2K and WinXP
machines at just over 10MB/s in a single stream and max out the 11MB/s
with two streams."  I am assuming he used the same client in that test
as he did with the test against Samba.  So from what he's said it
seems that he gets more speed with a Windows server than with Samba
for the same client.
