"The real approach is to reduce the working set of the Linux virtual
machines to fit in what you have available, instead of telling CP to
think that it has 2 or 3 times as much.

One way to reduce the working set size is to change the virtual
machines into 512M plus 256M VDISK for cache. It is almost as fast
(because VDISK is data-in-memory) but discourages Linux to use it as
cache. It could also be that the Linux server did not really need 768M
but someone just invented the number (or used this to run the GUI
installer).
If the 512M + 256M does not swap, you can probably lower the 512M and
see where it goes."

Rob,
Say you inherited a few linuxes and they are webservers, file servers, etc,
that
are set at 768M, 1024M, even 1536M. How do you tell what the working set
size
is? Is the wss indicated on the perfkit paging screen a valid indicator?
I can't necessarily get in to these linuxes either. :)

Thanks,
Mary Anne
