At least reading from the server is better now for some reason, close to 55MB/s, but writing to the Samba server is still around 1-1.5MB/s. Writing from Win XP is running at about 50MB/s to the Samba server isn't the problem. I also watched the smb process on the server when writing, just 1-2% CPU time and not much memory. The RAID LED indicators flashes with 3-5 seconds intervals, so it's not loaded down either. I'm certain it's a setting in Win7 that causes this, the question is what..
You might try the tricks mentioned in http://www.sysprobs.com/windows-7-network-slow .
Hope that helps.

Ismail, It helped a little. Now I'm up to 4MB/s which is still rediciously slow.. Oh well, I guess I'm stuck here for now, I'll post in some Win7 forums as well, and read anything I can find via Google.

What networking card do you have? If you are using Gb networks, jumbo packets (9014) help.... Most netgear switches support them....intel cards support them... I get better perf on win7 than on XP...so I'd wonder about the HW..... my XP gets 60-70 I think, while my win7 gets around 120-125MB/s writes, and about 115-119MB reads. But you are not alone in your grief....I see many complaints....which is why I wonder about the network cards and drivers.... Try an Intel Pro 1000 card.... My latest prob now is with the new Samba SMB2 support, I'm having to retune to avoid audio dropouts during large writes.... I reduced the number of transmit packets from 2048 down to 1024...that helped, may have to adjust more (too many other things going on as well to just test that)... Other settings on my card: Flow control: on adaptive interface spacing: adaptive interrupt moderation: enabled and set to 'low' jumbo packet: 9014 ipv4 checksum offload (rx&tx enabled) large send offload (ipv4 & 6) both enabled link speed & duplex = auto priority & VLAN: priority enabled (I don't have a VLAN) receive side scaling: enabled rcv buffers: 2048 xmt buffers: 1024 (reduced with SMB2) -- may need more tuning with the buffers tcp & udp, in both ipv4 & 6, offload: enabled: smart powerdown: disabled there are some other settings, but I don't think they'd affect perf. Have you tried a wireshark trace to see if it shows you any problems? I.e. compare it to the XP trace, and see what the diff is... could be a bad wire or connection and packet drops even...
