Jin Xu commented on MATH-1538:
------------------------------
>Did you benchmark this with a realistic use-case (i.e. within the class where
>this change is proposed)?
Not yet, but I don't think different use-case can affect this.
>any performance gain would be quite small
Yes, it is small. only 7% on my last test. and would be even smaller when array
size get smaller.
> refine some codes dealing with filling an array with its first and second
> elements.
