According to
https://github.com/JuliaLang/julia#Required-Build-Tools-External-Libraries
building Julia requires OpenBlas or Intel MKL. So the native
julia matrix-matrix-multiplication is most probably just a call
to a highly optimized BLAS gemm + some overhead.
=> beeing faster than Julia native would require to be as least
fast as openBLAS/Intel MKL gemm.
It would be nice to have such a good matrix multiplication in
Phobos but I think there are more important things to work on
(GC, AA, ...),
Dstep + cblas.h works quite well although code calling it
involves pointers :)
