> The take benchmark has three issues:
> 1. it is always taking the same element (indices is a constant vector), which is very easy to speculatively predict what the element is going to be.
> 2. It also does not compare with vs without nulls
> 3. all elements of the array are equal, which is again easy to speculatively predict
