I posted some before and after numbers when we merged Manfreds patch,
it would be interesting to see the same thing with your patch applied.

Im not only worried about NUMA bandwidth but keeping the amount of
memory left in all the nodes reasonably even. Allocating all the big
hashes on node 0 will decrease that balance.
