samba 3.0.26a-1 performance < 900 KiB/s, but FTP = 30-90 MiB/s

Let me start out by saing this is an oddball problem:

LINUX -> WINDOWS = < 900 KiB/s (varies between 100 - 900 KiB/s)
WINDOWS -> LINUX = 30-90 MiB/s (always)

Either direction, 30-90 MiB/s (always)

I do not see any nasty errors in the logs even with verbose = 5.

Any ideas here? I am not using any special options.

I found out that poor smb performance is related to a broken udp-perfomance of the 8169 NIC in outgoing udp.
But, only in Gb Mode of the 8169 NIC, with 100Mbps it is ok.

I had exactly the same problem with 100Mb/s also.

Solved by disabling onboard LAN interface and inserting (US Robotics) Realtek 8139 based card (10/100 Mbps).
