I found performance increased slightly with jumbo frames turned on,
between a Win 7 box and my main server running NetBSD/samba

.....I did hit that problem.
I have also had serious problems with realtek NICs in general though,
replaced my home NICs with intel stuff (just the 1000/pro pci and
pci-e cheap cards), everything is much more reliable now.
I also needed a switch that supported it or things just stopped
working (but reading your hardware specs it sounds like that's not a
problem you'll have. ;) )
Have you checked your SMB protocol level settings? The support for
SMB2 is quite new in samba, and it certanly wasn't enabled as standard
last time I checked. (This may have been a long time ago now.)
In your smb.conf, in the [global] section, try 'max protocol = smb2'
see if it helps.
I get about 40MB/sec to/from my samba box to my win7 box, which I
think is about the max my network supports (iftop watching a very
simple client/server sending data across a socket seemed to indicate
this speed too.)
