Hi Experts,

we have IBM  x3850 servers with below configuration, currently NUMA is disable.

Platform   CPUs    Cores    Sockets    Memory (GB)

Linux x86 64-bit    128    64    4    1009.61

we are facing performance issue on 4 node RAC. If we enable the NUMA, will it improve the performance on RAC node, since oracle aware about NUMA.
