You could create a, say, `@maybethreads` macro which depending on a global switch does the same thing as `@threads` or nothing, respectively. See [@assert alternatives? - #14 by WschW](https://discourse.julialang.org/t/assert-alternatives/24775/14) for a similar example. You might also want to check out [https://github.com/KristofferC/TimerOutputs.jl/blob/master/README.md#overhead](https://github.com/KristofferC/TimerOutputs.jl/blob/master/README.md#overhead).
