That can be true, but in a scale different from interpreted languages. For instance, in [this thread](https://discourse.julialang.org/t/fastest-way-to-check-for-inf-or-nan-in-an-array/76954/48) a highly optimized code obtains “only” a 6x speedup relative to the most natural implementations. Not 20x, 200x. The code without the optimization is still useful, and that optimization was a last resort. With other languages one simply cannot proceed before rewriting the critical parts, because the codes becomes too slow even for testing.
