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.
