>at first, the following scenario is used in our environment:

>Server-Side:
>- One Samba PDC using 3.0.24 release with TDB-backend.
>- Some Samba member servers serving files, home-dirs, etc.
>
>Client-Side:
>- Windows XP-Clients.
>- Windows Vista Clients (testing).
>- some Linux Ubuntu Distro (Feisty) Clients, using CIFS to access the 
>samba-shares.
>fstab-entry of the Ubuntu-clients:
>//server/share /media/files_on_server cifs 
>credentials=/home/user/.smbcredentials,dom=domain,directio,users,noperm,iocharset=utf8,nolock,soft,intr,rsize=8192,wsize=8192

>The problem:
>Since using release 3.0.25(a/b) on the samba-member servers,
>- accessing the shares by using a Linux Ubuntu Client through CIFS-mount is 
>very slow (!!!!). Sometimes you have to wait centuries to get the

>- accessing the shares by a Windows Client is at normal speed.

>After rolling back to 3.0.24 on the samba-member servers:

>What I've found out is:
>If we use Samba 3.0.25(a/b) on the member-servers and unset the "msdfs 
>root"-parameter from "yes" to "no", the
access-speed of the Ubuntu-Clients
>is at normal speed.
>Reverting the parameter to "yes" results in the mentioned problem.

>Rolling back to 3.0.24 and using "msdfs root = yes" results in NO
problem.
