Question:
        Can anyone confirm the following : Digital alpha servers use 8k
memory pages,
        and 8k i/o block sizes. Also, is there a way of verifying this
on a system ?

- You can verify the pagesize with the pagesize(1) command

- ADVFS uses 8K block sizes
 UFS uses 1k block sizes

- Another way to retrieve this info is with the library function sysconf
(_SC_PAGE_SIZE)
See the mmap() reference page for more hints.
