You will never obtain 1Gb/s, as that is the theoretical maximum.
Assuming that everything else in your network is running at 1Gb/s, and
there are no bottlenecks elsewhere, you should see at least 750Mb/s.

I guess the first question is what makes you certain that the problem
isn't on the Windows box?

Beyond that, I'd like to see the output from:
ethtool -i eth0
ethtool eth0
ifconfig eth0

How did you perform the measurements that you posted?
Are you sure that you're not hitting disk IO bottlenecks?
Is the problem only present with SMB, or other protocols as well?
