When I run the 50GB in-mem setup I still have 40GB+ of free memory, I drop the page cache before I run "sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'" there wouldn't really be anything to evict from page cache and swap isn't changing.
I think I'm crossing the numa boundary which means some percentage of the accesses are higher latency.
