How about running these benchmarks through a time profiler so you can see where the time is actually going?

  Sure! What exactly are you interested in?

    Your hypothesis is that MKL is taking the same amount of time and FFI overhead is the problem. A profiler could confirm your guess about MKL and tell you which part of the overhead is taking the time.

      I have to leave some exercises to the reader though ;)
