I am trying to figure out what these are.  The defaults are not good on a
large server.

The suggestion is figure out how much memory does dsmserv need and then work
from there.

So lets take the example of a 2G server with a buffer pool of 256MB and an
overall memory requirement of 400MB.  That would make you think there is
about 1.6GB left around.  Problem is the default filesystem maxperm is 80%
of the 2GB or about 1.6GB.  This would mean nothing left for the rest of the
processes, thus lots of paging.  I am thinking a buffer of about 128MB
should be in there.  So, in this case, maybe set maxperm to 65%.

The real question is what other vmtune knobs should be considered in a TSM
server.  The IO prefetch, large or small?  Is there a book on how to do
this?
