My intuition is that with, let's say, 500k entries "ets" should be
faster than "sets", since:
1) sets is essentially a very high degree tree, but still a functional
tree, which is still O(log n)
2) ets is a mutable hash table, which is O(1) with high constant factor

But even with high constant factor O(1) data structure will be faster
than O(log n) data structure after N is sufficiently high.

Please correct me if I am wrong :)
