They have not changed in any way, however there is a patchset proposed currently to change how NUMA works a bit. Unclear if it will change this situation.
Would that be a mysql or linux kernel patch (assume the latter)? Also want to echo xxjaba's comment further down - thanks for doing the work on that post, it was really enlightening!
Yes, a Linux kernel patch. I've got a lot of ideas on NUMA optimization for MySQL directly though, so keep an eye out for that, perhaps some time this year.
