I remembered that 3 months ago when Alex tested the numa/sched patches
there were 20% regression on SpecJbb2005 due to the numa balancer.
Those issues may have been fixed but we probably need to run this
benchmark against the latest. For most of the other kernel performance
workloads we ran we didn't see much changes.
Maurico has a different config for this benchmark and it will be nice
if he can also check to see if there are any performance changes on his
side.
