How can I arrange to only use @threads if the number of iteration is higher than minimum?

It’s a bit old, but perhaps still useful:

Conditional Multithreading

Is there a way to enable/disable calls to Threads.@threads? I’m developing an optimization solver, and when the problem is sufficiently small, using multi-threading hurts performance, and incurs allocations (my code doesn’t make any allocations until I wrap it in @threads). However, when the problem size grows and the individual operations being threaded become more computationally intensive (booting the arithmetic intensity) I get some good performance increases. I’d like to be able to enable…
