Just a quick hint: Single stream performance really heavily
depends on the concrete client behaviour. smbclient from 3.2
and higher should give you good performance. And watch out
which program on the Windows client you use to do the copy.
xcopy, robocopy and the Windows explorer on some OS version
give dramatically different results. The difference comes
from overlapping requests or their absence.
