It’s also relevant to note that your benchmark code is invalid in the sense of [PSA: Microbenchmarks remember branch history](https://discourse.julialang.org/t/psa-microbenchmarks-remember-branch-history/17436)

This doesn’t matter for your specific code, because it’s not branch-heavy. But you absolutely need a different benchmarking setup.
