[Bug 471512] Re: Slow cifs ubuntu 9.10

[uvi]

This problem still present in 10.10.

I discovered cifs module parameter 
parm:           CIFSMaxBufSize:Network buffer size (not including header). Default: 16384 Range: 8192 to 130048 (int)
But really it defaults to 4096.

I created  /etc/modprobe.d/cifs.conf  with
options cifs CIFSMaxBufSize=130048

Also I used cifs mount options rsize=130048,wsize=130048.

After setting rsize to max 130048, performance  increases!
