| Sep 28, 2016 at 0:48 | comment | added | Sander Heinsalu | Mathematica on Linux OpenSuse 13.1 was many times slower than on Windows XP on the same Dell D630 PC. Both starting up slow and running the code slowly. | |
| May 10, 2016 at 19:38 | comment | added | Szabolcs | I noticed this too: I ran Mathematica directly on OS X, on Windows in VirtualBox and on Linux in VirtualBox. On the same hardware. Generally, Windows was a bit faster than OS X and Linux was a bit faster than Windows. | |
| Dec 29, 2015 at 21:18 | comment | added | Shredderroy | I had exactly the same set-up on an early 2014 MacBook Pro, on which I ran Mathematica in OS X as well as on Windows 8.1. And I found exactly the same characteristics: Mathematica ran faster in Windows 8.1 than in OS X. | |

You may want to use SeedRandom to make sure you are working on the same matrices. On your a.b example I could observe variations of up to 20% on just 10 trials.

add info to the question

Why not run Needs["Benchmarking`"];Benchmark[] for a full comparison?

I'm not on Mac so I can't test this, but I believe that on Windows Dot on packed reals is implemented as a fast Intel® Math Kernel Library call. I am guessing that on the Mac such a call isn't being used for some reason. Perhaps a driver or library is missing; perhaps the developers never bothered to implement it.

MATLAB changed to Mathematica

| Aug 4, 2013 at 19:33 | comment | added | Code Different | You guys are right. I'm did copy the code so messed up the function name. It's corrected now. | |

corrected the function name

To begin with the function name is RandomReal not RandomReals. Did you copy this code exactly?
