Round-robin has does not really work with processes which produce 
different loads as those processes would have to move to other CPUs 
later to be ale to run. This involves reloading of CPU caches.

The whole problem is not this simple.

NUMA adds here as the memory content is local to CPUs too. Moving a 
process to a neighbour is still not this bad compared to moving it to a 
different CPU node.
