Edit: here some benchmarking information. Windows is running in Bootcamp in the benchmark, not from VMWare Fusion:

Mathematica on Mac seems to be a good 20% slower than on Windows.

I recently got a trial version of both Mathematica 9 and MATLAB 13a for Windows. I was stunned by the performance difference in the Windows and the Mac version. It was a simple test in matrix multiplication. Here's the code:

a = RandomReals[{0,1},{1000,2000}];
b = RandomReals[{0,1},{2000,3000}];
Timing[a.b;]

On Windows, running on VMWare Fusion, the above code takes 0.17 second to complete, more or less same as MATLAB. But on the Mac, it takes 1.8 seconds, or 10 times longer to complete the calculation. Something is terribly wrong here. Is there anything I should do to optimize the performance of Mathematica on my Mac Mini?

Something is terribly wrong here. What can be the explanation for this discrepancy? (I have 12GB free RAM on my 2012 Mac Mini so we can rule out memory shortage).
