To answer a question in the comments, for bytes I'd use a lookup table. You can generate it at runtime:
counts = bytes(bin(x).count("1") for x in range(256)) # py2: use bytearray

public static long fibonacci(int x) {
return memo.computeIfAbsent(x, n -> fibonacci(n-2) + fibonacci(n-1));
}
As you can see, the method computeIfAbsen...

There's a dynamic_cast of the locale that doesn't get hoisted out of the per-char loop. See my answer. On the plus side, this may be properly UTF-8 aware, but the slowdown doesn't come fr...
