For the implementation of a paging scheme, suppose the average process size be $x$ bytes, the page size be $y$ bytes, and each page entry requires $z$ bytes. The optimum page size that minimizes the total overhead due to the page table and the internal fragmentation loss is given by $\frac{x}{2}$ $\frac{xz}{2}$ $\sqrt{2xz}$ $\frac{\sqrt{xz}}{2}$
