[Samba] Slow performance with cifs client

[Praise]

Hi all.
I have a problem with the cifs module in my gigabit network.
I get the following performance:
95 mbytes/s with FTP
65 mbytes/s with samba, windows 7 client
8 mbytes/ with the cifs module on opensuse 11.4

I have tried all the solutions  found on google,
such as directio, modifying rsize and wsize, with
no improvements. Any advice?

Is this the right place to discuss issues with cifs?
