It is quite surprising that there is this much of a difference,

You should definitely have a look at this benchmark for matrix
multiplication across a many languages:
https://github.com/kostya/benchmarks#matmul
With the recent generic GLAS kernel in mir, matrix multiplication
in D is the blazingly fast (it improved the existing results by
at least 8x).
Please not that this requires the latest LDC beta with includes
the fastMath pragma and GLAS is still under development at mir:
