Significantly slower broadcasting

I have been testing the speed of broadcast operations with OffsetArrays of StaticArrays, and it looks like there is a significant penalty in time. In fact, on my laptop I see

julia> using StaticArrays, OffsetArrays, BenchmarkTools

julia> xs = [SVector{2}(rand(2)) for _ ∈ 1:10_000];

julia> ys = similar(xs);

julia> @benchmark (@. $ys = $xs / (first($xs)^2 + last($xs)^2))

When using OffsetArrays instead these are the results:

julia> oxs = OffsetArray(xs, -1000);

julia> oys = OffsetArray(ys, -1000);

julia> @benchmark (@. $oys = $oxs / (first($oxs)^2 + last($oxs)^2))

The $> 5 \times$ penalty is even larger than the SIMD vector size of my laptop (4 for Float64 arrays).

Any help or clarification is really appreciated!

Start by reproducing the Julia benchmark comparing broadcast operations on OffsetArrays of StaticArrays with ordinary arrays. The issue names no source files or tests and does not specify a requested code change; done would require determining the cause of the reported slowdown and either fixing it or documenting the explanation.
