I think you currently pay quite a performance price for implementing the
compare methods in such a ways that they delegate to the `ByteComparator` and
`FloatComparator`. In order to call those, every single byte or float need to
be boxed.
That can be avoided if the method directly implements the array comparisons
on the primitive types.
