I see that you have tried to quote your code, but it’s not quite right. Please take a look at this post to see how to format code for discourse: [PSA: how to quote code with backticks](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530)

You should also remember to interpolate variables when using BenchmarkTools: `@benchmark test($m)`, instead of `@benchmark test(m)`. It may not make a difference here, but in general, it does, and it removes the need to double-check if performance issues are due to the lack of interpolation.
