[wplug] SMB connection slowing down

[Alexandros Papadopoulos]

I'm copying a 130MB file from an SMB-mounted partition on a remote NT4 
server, to my linux box. The server has a 100MBit NIC, the linux box is 
on a 11MBit wireless link. They're both practically on the same switch.

Ping from my linux box to the NT server reports:
7 packets transmitted, 7 received, 0% packet loss, time 6056ms
rtt min/avg/max/mdev = 3.312/3.426/3.684/0.139 ms

Although right after issuing the cp command, a couple megabytes get 
transferred quickly (the first 10MB take less than 30 seconds), it's 
now 4,5 hours (four and a half HOURS) later, and it has transfered 97MB 
of the file in question. With a back-of-envelope calculation, that 
works out at roughly 6KB/sec, which is pathetic for a LAN.

I stopped and re-issued the command, while sniffing with Ethereal. I 
singled out the TCP stream, and then graphed for throughput, which gave 
about 250KB/s. It's slowing down as it goes.

I don't have the first idea how to troubleshoot this, any suggestions?

Thanks
