which Windows  and which CentOS (6, 7) you are talking about?

how do you copy from CentOS to CentOS - SMB, too?

this seems to be, that SAMBA doesn't support SMB v2 or v3

can you try the following test, to see if it is not a problem deeper ...

can you get WinSCP ...
https://winscp.net/eng/download.php
(the Portable executables suits)

and connect with this from Windows to CentOS and try a file transfer here
if it has nearly the same speed as with SAMBA, the problem is deeper
if it is quite faster then the problem is SAMBA
