1. You’re timing in global scope, so your results are not going to be informative. For a discussion of the same issue from earlier today, see: [How to assign real/imaginary part of complex array - #11 by rdeits](https://discourse.julialang.org/t/how-to-assign-real-imaginary-part-of-complex-array/10818/11)

2. You’ll get substantially better performance if you use [https://github.com/JuliaArrays/StaticArrays.jl](https://github.com/JuliaArrays/StaticArrays.jl) for your small fixed-size attrays.
