216 Select the kernel logical page size. Increasing the page size
217 will reduce software overhead at each page boundary, allow
218 hardware prefetch mechanisms to be more effective, and allow
219 larger dma transfers increasing IO efficiency and reducing
220 overhead. However the utilization of memory will increase.
221 For example, each cached file will using a multiple of the
222 page size to hold its contents and the difference between the
223 end of file and the end of page is wasted.
