This lets you select the page size of the kernel. For best
performance, a page size of 16KB is recommended. For best
compatibility with 32bit applications, a page size of 4KB should be
selected (the vast majority of 32bit binaries work perfectly fine
with a larger page size).
4KB For best 32bit compatibility
16KB For best performance
64KB For best performance, might give more overhead.
If you don't know what to do, choose 4KB.
