"AIX has optional support to recognize the division of system memory among
the MCMs. If the memory affinity support is enabled, AIX attempts to satisfy
a page fault using memory attached to the MCM containing the processor that
caused the page fault. This may provide a performance benefit to the
application."

I hope not!  Isnt the SLS supposed to make all page faulting transparant
even to the OS?  What with memory pools on the iSeries, shouldnt the SLS
ignore the connection between processor/MCM and its attached system memory?

On a multi processor iSeries, can memory pools be assigned to a processor?
