What is the difference between adding a secondary swapfile and adding
a secondary pagefile.  The documentation says that both files can be
used for swapping or paging.  

Our situtation is that the system never pages (well, almost never),
but has been running out of swap space.  Actually, it has been
reporting that the swap space is badly fragmented.

Should we add a swapfile or a pagefile, and why?  

Also, given that our system never swaps or pages, does it matter (in
terms of performance, I guess) that we don't have enough contiguous
space for the secondary file (and have been creating it
non-contiguously)?
