Public bug reported:

Binary package hint: samba

Hi

I'm running feisty (Linux animal 2.6.20-15-generic #2 SMP Sun Apr 15 06:17:24 
UTC 2007 x86_64 GNU/Linux
) as my principal desktop in a small mixed network of Windows, Macs and Linux.  
We use Samba as our common file sharing protocol across the gigabit network 
(lowest common denominator...)

Since the upgrade from edgy to feisty I've been having problems
distributing files from my desktop using Samba.  Transfer speeds are
ridiculously slow (50 kb/s). The problem manifests either as me sitting
at the feisty desktop and copying files to other machines, or from other
machines copying files off the feisty desktop.  However copying files
*to* the feisty desktop is fine (5s to copy 100 Mb typically).  The
problem seems to be independent of the machine connecting to my feisty
desktop - XP machines and another Linux box running Mandriva all show
the same symptoms.  Transfers between all other machines on the network
via samba is fine. I don't experience any samba browsing problems either
to or from the feisty machine.  I've replicated the slow transfers using
the Nautilus browser and from the command line.

NFS transfer speeds to and from the feisty desktop to the other linux
machine are fine.

One interesting symptom is that if the feisty box is also receiving data
via the network (can be anything, downloading off the internet for
example) then the samba transmission speed goes up to normal for the
duration of the download and then drops down to the very low speed as
before. Weird.

I've tried mucking about with the various network parameters
(TCP_NODELAY etc), enabling and disabling WINS support and the 'msdfs'
fix.  My smb.conf is entirely 'out of the box', save for changing to
'share' security and enabling a couple of shares.

Thanks
