It doesn't though. It still retrieves up to the bucket size, so with a
little cache poisoning (or a series of unfortunate events) it will be no
better than before.

Perhaps open with the problem statement. What is it you are trying to
fix? Would adding metrics to the buffer cache be a good start to
demonstrating what needs improving?
