Hi,

I ran SPECjbb with and without NUMA settings on polwarth, the scores are 
indifference:

Baseline:
RUN RESULT: hbIR (max attempted) = 49322, hbIR (settled) = 45720, 
max-jOPS = 43897, critical-jOPS = 25566

With NUMA enable:
-XX:+UseNUMA -XX:+UseNUMAInterleaving -XX:+AlwaysPreTouch

RUN RESULT: hbIR (max attempted) = 49322, hbIR (settled) = 47744, 
max-jOPS = 43897, critical-jOPS = 25848
