Description
Especially for the sorts based on int[], this avoids boxing potentially huge numbers of ints. Even for classes, it avoids unnecessary casting and expensive Array.Get/SetValue calls, and switching to a delegate avoids a top-level allocation for the comparer inside the current Array.Sort implementation.
Customer Impact
Unnecessary allocation, interface dispatch, expensive Array.Get/SetValue calls, etc.

No
