Which is better for performance on large Red Hat 5 systems (64gb+
memory, 8+ cpu's) - using 10g style shm settings and hugepages, OR the
newer 11g Automatic Memory Manager (which does not support hugepages).
The system I am building is a 6 node 11g R1 RAC, memory somewhere
between 64gb and 256gb (not sure yet), 8 cpu per node. This machine
will support a huge workload.
