Heya, for standard arrays that are small, the einsum-macro from Einsum.jl can be faster than BLAS. Einsum.jl translates the code simply into three loops and if cache-access patterns (presumably what most of BLAS optimisation is concerned with) isn't an issue, the for-loops are very fast. A quick check shows that for a simple matrix multiplication, Einsum is faster for 5x5 matrices but slower for 10x10. (This is ignoring the compilation-time that calling a julia function for the first time incurs)
