What portion of source would I need to modify to change the memory page
size?

I ran across some info stating that a current optimum page size for
IA64-Linux is 16KB; any validity to this?

Are there any major side effects of changing the page size?

---------------------------
We are porting and beginning to benchmark a subset of high performance
applications, are there any other recommendations for optimizing the Linux
kernel, or is there a better tuned kernel available anywhere?

Thanks.

Mike-

You are correct, page size is a compile time constant, you cannot change
it at run time.

The `getpagesize' GLIBC function returns the kernel's page size.
