the variant of rand! for an array of Float64 is slowed down by the explicit SIMD when the array is small enough #57114
Description
Benchmarking #57101, I notice using the implementation with explicit SIMD is slowing down rand!(::Memory{Float64}) for arrays shorter than about a thousand elements. Perhaps a cutoff would be good, to only use the SIMD-ed implementation for large-enough arrays. Will investigate more deeply later.
