Here are the specjbb results on a 2 node 24 GB machine.
vm_1 was allocated 12 GB, while vm_2 and vm_3 were allocated 6 GB each
All vms were running specjbb2005 workload
All numbers presented are improvements/regression from v3.7-rc8

there are couple na's .. In those case, the testlog for some wierd
reason didnt have any data. this somehow seems to happen with tip/master
kernel only. May be its just coincidence.
