Of course it's slower. The IEnumerable interface expects a class with methods you have to call to maintain which item in the IEnumerable implementor you're looking at.

Calling methods adds overhead, and plenty of it compared to the overhead of an index variable, which you know is just pointer math.

Enumerable being slower is not surprising at all. Just don't use it where you don't have to, and that includes LINQ because it's heavily dependent on the IEnumerable interfaces.
