No, Gad, you showed no such thing.  

You compared different database servers on different operating systems, and
concluded it was "obviously" FreeTDS.  When I pointed that out, you posted
no response.  When I suggested a plan better suited to yielding the
information you seemed to want, you answered me with refutation.  

If you're genuinely interested in scientifically investigating database
server and protocol performance, you need a better methodology than you've
employed to date.  I will help because if you do discover something, I'd
like to know about it.  If on the other hand you just want to publish
embarrassing non sequitur conclusions, please go ahead and be my guest.
Just don't expect any engagement here.  

The choice is yours.
