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? I started asking around collegues and others, on the internet too, and I found that almost everybody I know have performance problem with cifs. If needed, I can test some new version of the driver to help your job. I am a C programmer, even if I am not a kernel programmer and I don't know the CIFS protocol JM
