really .. I should move thousands of smaller files .. and then perhaps try
a direct gigabit to gigabit connection between two samba servers.

I could easily hook up an AMD Opteron here ( Solaris 10 ) to a Sun
UltraSparc box with point to point gigabit just to see what the transfer
rate maxxed out at. Any combination of switches and routers will result in
a lower number so .. may as well do CAT6 end to end and point to point
just to see what I get.
