[Bug 471512] [NEW] Slow cifs ubuntu 9.10

[biebel]

Public bug reported:

Binary package hint: smbfs

Ubuntu 9.10
mount.cifs version: 1.12-3.4.0

Transfer speed over samba using CIFS/SMBFS has dropped severely since updating to 9.10 (clean install).
I should be getting transfer speeds of +- 8 MiB/s, but I'm only getting +- 4 over CIFS.
As I still get the expected 8 MiB/s when copying via gnome (Places => Network) and in windows, I'm quite sure it is a CIFS problem.
For some odd reason pushing files from the server to a shared folder on my main computer used to go @ the full 10 MiB/s under 9.04. Now with 9.10 installed on the server it won't go over 2 MiB/s.

I have tried many rsize= arguments, but every value I've tried only made
things worse.

Steps to reproduce: 
Mount share using mount -t cifs
Copy file
