Summary:
Seeing improvement on a 2 node when running autonumabenchmark .
But seeing regression for specjbb for the same box.
Also seeing huge regression when running autonumabenchmark
both on 4 node and 8 node box.
Below is the autonuma benchmark results on a 2 node machine.

Here are results of specjbb run on a 2 node machine.
Specjbb was run on 3 vms.
In the fit case, one vm was big to fit one node size.
In the no-fit case, one vm was bigger than the node size.
