Perfect... exactly what I was looking for.  Thanks!

I didn't include it because it didn't change across my comparisons, but here
it is:

#Global parameters
        workgroup = MSHOME
        netbios name = NAS3
        security = SHARE
        server string = Samba Server
        log file = /var/log/samba/%m.log
        max log size = 50
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        encrypt passwords = yes

        comment = RAID5 Share
        browseable = yes
        path = /data
        force user = nobody
        force group = nobody
        read only = No
        guest ok = Yes

I haven't tried playing with the socket_options.  Tweaking those would
perhaps change my performance of the smb tests, however it still wouldn't
explain why smb over linux is much slower than smb over windows.
