I see (via "make xconfig") in SLES8 that Pseudo Page Fault support is enabled.  The 
associated help says that if the PFAULT macro cannot be used then PAGEEX (sic) will be 
used.  However, to use PFAULT the virtual machine must be in XC-mode operation, 
according to the IBM CP Programming Services manual.  The SLES8 install doc shows a 
sample directory entry with MACHINE ESA specified.  Also, when I issue a CP QUERY SET 
it shows that PAGEX is OFF.  I gather from these facts that Pseudo Page Fault support 
must not be actually in use.  Some questions: 

- Should we be running with MACHINE XC specified in the directory entry for the SLES8 
servers?
- If not running MACHINE XC, should I be specifying SET PAGEX ON before booting SLES8?
- Finally, and more generally, should I even bother?  That is, will Pseudo Page Fault 
support make running SLES8 faster?

Thanks for any insight that you may have on this topic.
