It seems that Mathematica has a much closer performance to Matlab in the matrix vector mulplitcation than that of the matrix vector multiplication.

It seems that Mathematica has a much closer performance to Matlab in the matrix vector mulplitcation than that of the matrix number multiplication.

I'm happy about the <2X slowness in the matrix vector multiplication, but the slowness of the matrix number multiplication seems to me like something is not working properly, given that this operation is so fundamental that it should have been optimized at an early stage.
