Of course it isn't fair. But if you want to draw useful conclusions from a 
benchmark, you have to do what is known as "isolate the variables". If there are 
two independent variables feeding into performance, you CANNOT draw a conclusion 
about one of them from the performance. In other words, if:

    g = f(x,y)

then knowing g, x and y tells you nothing at all about x's contribution to g.
