samba - Mar 2011 - Speed problem Ubuntu < WD TV Live

Dear all,

I have experiencing some speed issues recently when moving files using
Samba between a linux box (Kubuntu 10.10) and a media player called WD
TV Live.

Both are wired to a 100 Mb network, together with a Windows 7 box. In
principle I believe is not a hardware issue. When I move files between
the WD TV Live and the Windows box I get speeds of around 8 MB/s.
Between Kubuntu and WDTV I get less than 1 MB/s.

I have tried booting from a live version of Kubuntu and still the same
speed issue. However, moving files from a Knoppix live speed is fine.
It seems a (K)Ubuntu problem.

By default Ubuntu ships with smbclient 3.4.7. I have also installed
samba4-clients, which replaced smbclient. I did purge all
configuration files before updating. I believe the samba version in
the WDTV is 3.5.4.

I haven't seen significant differences between kubuntu and knoppix at
kernel level.

Any orientation would be much appreciated... i'm starting to be desperate
:-).

Thanks,

Hi again,

I'm not sure if my messages get through, as I don't receive a copy...
a confirmation would be much appreciated.

I have some additional information on the speed problem...

Now I'm using a completely different card, the one integrated in the
motherboard: nVidia Corporation MCP55 Ethernet. Speed a bit higher,
but still slow (around 1.4 Mb/s).

Something really weird I have found... if I send two files at the same
time, I get double speed, triple if the number of files is three. So
it doesn't seem like an overall bottleneck, but more at a file level.

Another piece of information... I managed to boot the computer with a
different linux distro (Slax) and I have the same speed problem, so it
might not be a distro-related problem.

I'm not sure if posting logs would help...

Thanks for your help! I would loose hair with this issue if I wouldn't
be bald already...
