Note that such cache-oblivious algorithms cannot be trivially applied to
any problem. Also, properly written cache-oblivious algorithms tend to
recursively decompose the problem until it is small enough to fit in a
cache and solve each part iteratively. The improvement effect can be
noticed on large inputs. These algorithms will most probably perform quite
badly on small inputs.
