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

If unsure, choose 4K_PAGES.
