One change which I'm currently making is to use kmalloc_node() instead of kmalloc() for the per-NUMA node, and I suspect *that* is going to make a quite a lot of different on those systems where the ratio of remote to local memory access times is larger (as I assume it probably would be on really big systems). - Ted
