samba - Jul 2003 - Samba 2.2.7 and 3.0.0b3 slow transfers with Win2k and WinXP

Hi all,

I'm thoroughly stumped.  I have a network of Windows 2k and Windows XP 
Professional machines working off of Samba served home directories. 
Everything works.  Sign-ons are relatively quick, no odd errors in the 
samba logs or on the Windows boxes, and all the configuration seems to 
work fine wrt all functions.  Name lookups via nmblookup or nbtstat work 
fine (though it looks like only broadcast lookups are working for the 
Windows machines, even though I have nmb running--I'm probably missing 
something there).

However...The samba shared directories are horribly slow on the Windows 
machines.  They run at about a 1/6th the rate of locally mounted 
directories or NFS mounts from the same server.  Not only that, but a 
Linux box can mount the samba share and access it at about the same 
speed as NFS or a local FS.  In short, everything is fine except all of 
the Windows machines take ages to do anything.  Though there is nothing 
in the logs, the CPU is pretty high (~50% for one client) when copying 
large files, or building software.

Worth noting...I've tried with and without 'socket options'.  And
the
behavior is seemingly identical on both 2.2.7 and 3.0.0b3 versions.

This has been plaguing me for months...Anyone have a clue?

Is there a way to detect who is logged into the domain with a samba PDC?
I would do some operations only if the user is logged in.

Try smbstatus -u username ... grep username
but this work only if your user have mount any share simply home from domain
logon script.

Bye.
