Yes, I've forgot to mention that I can also get link saturated with single Win client, therefore it does not appear to be a server issue. BTW: Slack, samba compiled from scratch (v3.4.5) and custom vanilla kernel (but nothing fancy or unusual).
b. PS: The funny thing is, as I recall, I did previous samba setup 5 or 6 years ago, and I distinclty remember I was running into the same issue, at more or less the same speed.
