Yes, a very specific implementation will be faster than a generic system which includes network delays and ensures you can handle things larger than your memory in a multi-client system. But the result is meaningless - perl or awk will also be faster here.
If you need a database system, you're not going to replace it with K, if you need super fast in-memory calculations, you're not going to use a database system. Apples and oranges.
