Wouldnt go so far to say that they are unreliable, but there is certanly some problem between Samba and 8169 driver (and maybe other driver, don't remember for sure, but will check first thing in the morning)

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.
Solved by disabling onboard LAN interface and inserting (US Robotics) Realtek 8139 based card (10/100 Mbps).
Thank you for your response, so the bottom line is Realtek 1Gbps NICs are unreliable. Wonder what Realtek has to say about it if they even respond, added them to cc list.
