Hi all,
Disregard my previous posts, I've consolidated everything here.
I'm having terrible performance issues with samba over a WAN
(point-to-point T1 link).
Doing a copy of a 2MB file from a samba server to a linux client
running smbclient takes over 5 minutes.
SCPing the same file takes seconds.
The server is running samba version 3.0.25c with kernel 2.6.16.18.
I've put up a set of debugging logs at:
http://emagiccards.com/james/sambalogs.tar.bz2
Inside are 3 files:
smb.conf - the configuration of the samba server
log.agard - the level 10 debug log of the copy from samba
samba-tcpdump.log - a tcpdump log from the client side of the copy
Any help to fix this issue would be greatly appreciated since the file
server is pretty unusuable over the WAN.
If you need any more information, please let me know. It is imperative
that I find out what's happening here.
Thanks.

One of the other things that I've noticed is that the pattern of Data
/ Acks is different based on where I connect from.
If I connect on the server side of the T1 link, the data / ack pattern
seems to be:
Server sends 1500 byte packet
Server sends 1500 byte packet
Server sends 1500 byte packet
etc...(to 64k)
Client sends 52 byte ACK
Client sends 52 byte ACK
Client sends 52 byte ACK
etc...
If I connect from the other side of the T1, the data and acks are interleaved:
Server sends 1500 byte packet
Client sends 52 bye ACK
Server sends 1500 byte packet
Client sends 52 byte ACK
etc..
Can anyone think of a reason for this?
MTU of T1 link ? Try decrease it.

Thanks.
